maint: avoid new warning from gcc (GCC) 7.0.0 20160503 (experimental)
* src/id.c (main): When configured with --enable-gcc-warnings and using
the very latest gcc built from git, building would fail with this:
src/id.c:200:8: error: assuming signed overflow does not occur when \
simplifying conditional to constant [-Werror=strict-overflow]
bool default_format = (just_user + just_group + just_group_list
^~~~~~~~~~~~~~
Rewrite to use bool-appropriate operators.
