BaseTools/GetFw: Skip R_X86_64_NONE relocations
Building .aslc files in a module for host-based unit
testing in Linux/GCC X64 environments may introduce
relocations for a symbol in a shared library from
lcov or asan.
Update logic to not generate an error message and exit
if the symbol is unknown but the relocation type is
R_X86_64_NONE.
