runtime/cgo: add .file directive to GNU assembly files

Without it, at least on ARM64 with older BFD linker, it will
include the file of the object file (which is of a temporary path)
as a debug symbol into the binary, causing the build to be
nondeterministic. Adding a .file directive makes it to create a
STT_FILE symbol with deterministic input, and prevent the linker
creating one using the temporary object file path.

Fixes #57035.
