maint: refactor unsetenv call in env

Keep unset envvars (-uFOO) in an array for later deletion,
instead of reiterating over argv.  Done in preparation for
'-S string' feature. Related to '-u' discussion in
https://lists.gnu.org/r/coreutils/2018-04/msg00013.html

* src/env.c (append_unset_var,unset_envvars): New functions.
 (main): Use new functions.
