[release-branch.go1.18] cmd/link: stop passing -pagezero_size to darwin linker

We added -pagezero_size in CL 72730, where it was intented for iOS.
The current code passes it only on macOS/AMD64 instead. It is not
really necessary there. Also, the new darwin linker starts to emit
a warning about deprecation of the flag. Stop passing it.

For #55113
Updates #54482, #55112.
