runtime/cgo: ignore -Watomic-alignment in gcc_libinit.c
When cross-compiling a cgo program with CC=clang for Linux/ARMv5,
atomic warnings cause build errors, as cgo uses -Werror.
These warnings seem to be harmless and come from the usage of
__atomic_load_n, which is emulated due to the lack of atomic
instructions in armv5.
Fixes #65290
