Fix build tags for user_other file.

[Toasterson]

During the compilation of gitea on illumos I ran into the issue that both user_posix.go and user_other.go where considered for inclusion by the golang compiler with golang 1.18.

This PR forces the golang compiler to exclude user_other on all platforms mentioned in user_posix.

Testing on Windows should be done for this PR as I do not own any Windows machine and it is likely that user_other.go also conflicts withuser_windows.go.

What is your GOOS ?

[Toasterson]

GOOS="illumos"

GOOS=illumos go test -c seems to work.

I don't know why you're having problems; with the current //go:build js || android || hurd || zos || wasip1 it should not build on illumos. Maybe something strange in your setup? Or something else?

Since this is a few years old I'll just go ahead and close it, but feel free to come back if you're still having problems.
