enter_chroot: auto generate user locales
Since we no longer force LC_ALL=C on everyone, the few times that perl
does get run by people, it spews the expected "Setting locale failed"
warnings. This isn't as big a deal as with Debian systems as perl usage
is uncommon in Gentoo.
This is also highlights the long-existing small issue of only specific
locales being available in the chroot. So for non US english speaking
users, they've been having non-optimal experiences.
So parse the user's active locale and automatically generate the missing
ones in the chroot so that when they do enter, things "just work".
BUG=chromium-os:19139
TEST=set locale to non-existent ones, enter_chroot, & verify locales are created
