This solves two problems (and half):
a) messing with user's preference file is a no-no, if we want a
hardcoded behaviour like this, profile.d is the way to go
b) .bashrc settings are overridden when doing env-update; source
/etc/profile
c) profile.d will also apply to root (although not with sudo su)
BUG=none
TEST=below
1) ./run_chroot_version_hooks --version 21
2) see all fixed, source /etc/profile, and still see my prompt unchanged
