sys-libs/glibc: guard against rendering system unusable, bug #627338
For cases like FEATURES=config-protect-if-modified
or custom /etc/nsswitch.conf with only 'compat' resolver
and external providers glibc upgrade will break local
user resolution when switching from older glibc.
Bad /etc/nsswitch.conf:
passwd: compat
shadow: compat
group: compat
Good /etc/nsswitch.conf:
passwd: files
shadow: files
group: files
Ok /etc/nsswitch.conf:
passwd: compat files
shadow: compat files
group: compat files
