BaseTools/GenFw: Fixed R_AARCH64_CALL26/R_AARCH64_JUMP26 when referring to start of a section

When R_AARCH64_CALL26/R_AARCH64_JUMP26 relocations referred to static
functions, they sometime refer to the start of the '.text' section + addend.
It means the addend is different of '0'.
The non-patched code (before applying the relocation) already contains
the correct offset.
