From kernel v5.2 task_struct member cpus_allowed is changed
to cpus_mask. Add a change to read cpus_mask in case kernel
version is greater than 5.2.

Since kernel v5.0, there is a dedicated region of size 128MB
kept aside for BPF programs(BPF_JIT_REGION) which were
previously using module region. Also in v5.4, kernel VA space
was flipped to accomodate support for kasan shadow and 52bit VA.
Hence we are updating the VA space calculations in parser to make
it work on newer kernel.

Adding few changes on linux banner read and match for cleanup.

There was an unmonitored variable ramdump.version being used in
debug_image_v2 cauing version check failure. Adding a change to
use kernel_version.
Fix intend in debug_image_v2.

Briefly, the calculations are updated as below:

_PAGE_END(va)		= (-(UL(1) << ((va) - 1))) = 0xffffffc000000000
KASAN_SHADOW_END	= (_PAGE_END(VA_BITS_MIN)) = 0xffffffc000000000
BPF_JIT_REGION_START	= (KASAN_SHADOW_END)
BPF_JIT_REGION_SIZE	= (SZ_128M)
BPF_JIT_REGION_END	= (BPF_JIT_REGION_START + BPF_JIT_REGION_SIZE) = 0xffffffc000000000 + 0x8000000
MODULES_VADDR		= (BPF_JIT_REGION_END)
MODULES_END		= (MODULES_VADDR + MODULES_VSIZE) = 0xffffffc000000000 + 0x8000000 + 0x8000000 = 0xffffffc010000000
KIMAGE_VADDR		= (MODULES_END) = 0xffffffc010000000

When parsing kernel module symbols retrieved from kallsyms
nodes, lrdp-v2 will unconditionally add address 0x0 when seeing
it, which causes task stack unwinding showing a particular
module's name for address 0x0.

Add symbol address checking when parsing info retrieved from
module specific kallsyms nodes, to avoid adding address 0x0 as
undefined symbol for a particular module.

Add code to retrieve module specific symbol info from per-module
kallsyms nodes when CONFIG_KALLSYMS is defined. Symbols retrieved
from kallsyms nodes will be more accurate because relocation
has already been done when the per-module kallsyms nodes are
formed.

Add the following options to control how the symbol info will
be recorded in lrdp-v2 output files:

--dump_mod_sym_tbl: dump per-module symbol info retrieved from
                    module specific symbol files.
--dump_krnl_sym_tbl: dump Linux kernel symbol info retrieved
                     from the kernel symbol file.
--dump_mod_kallsyms: dump per-module symbol info retrieved from
                     per-module kallsyms node.
--dump_glb_sym_tbl: dump everything in the global symbol lookup
                    table.
