ANDROID: KVM: arm64: Ignore modules with empty .hyp.text section

Modules with an empty '.hyp.text' section do not contain any EL2 code
and should therefore be ignored for the purposes of hypervisor module
loading. Failing to ignore such modules will likely result in a later
loading failure due to the absence of '.hyp.reloc', which is not present
for non-hypervisor modules.

Don't bother parsing the other '.hyp.*' sections for modules with an
empty '.hyp.text' section and return early success to allow the module
to load as a normal kernel module.
