syscall: fix creds_test to reliably close os.File

Uncovered by Uros Bizjak.

Before this patch the test would close the file descriptor but
not the os.File.  When the os.File was GC'ed, the finalizer
would close the file descriptor again.  That would cause
problems if the same file descriptor were returned by a later
call to open in another test.

On my system:

> GOGC=30 go test
--- FAIL: TestPassFD (0.04 seconds)

Avoid conservative behavior in REE by allowing removal of redundant extends

in merge_def_and_ext only calls combine_set_extension if the candidate for
