[PATCH] wrapper: remove xunsetenv()

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

Platforms that are using the git compatibility layer for unsetenv
use void as a return value for unsetenv(), so any function that checks
for a return value will fail to build.

Remove the unused wrapper function.
