seccomp: passthrough uprobe systemcall without filtering

Adding uprobe as another exception to the seccomp filter alongside
with the uretprobe syscall.

Same as the uretprobe the uprobe syscall is installed by kernel as
replacement for the breakpoint exception and is limited to x86_64
arch and isn't expected to ever be supported in i386.
