maint: minor cleanup

The previous commit introduced a couple of syntax-check failures.

* .gitignore (/lib/se-label.h): Add entry to silence the
sc_gitignore_missing check.  Sort entries in C locale.
* po/POTFILES.in (src/selinux.c): Remove entry as this source doesn't
contain any translatable strings anymore; avoids a sc_po_check failure.
* src/mv.c: Replace tabs by spaces to avoid complaints by
sc_prohibit_tab_based_indentation.
