static_call: Fix the module key fixup
Provided the target address of a R_X86_64_PC32 relocation is aligned,
the low two bits should be invariant between the relative and absolute
value.
Turns out the address is not aligned and things go sideways, ensure we
transfer the bits in the absolute form when fixing up the key address.
