syscall: remove "use" function and calls from generated code.

Update syscall code generators to set build tags.

Regenerate zsyscall files, which makes the following changes:
- remove calls to "use"
- update build tags, adding missing ones in some cases
- "stat" renamed to "st" in some cases
- "libc_Utimes" renamed "libc_utimes" in one case

I'll mirror this change to x/sys/unix once committed.
