Import profile from bashrc if profile has not been loaded

On Debian 11, opening a terminal with bash will run a bashrc file
without the profile. The bashrc expects profile to be loaded, so it will
load the profile.

To avoid circular imports, .profile will set __PROFILE_LOADED__ and the
bashrc file will load the .profile if that variable has not been set.
After that check, bashrc will unset __PROFILE_LOADED__ as cleanup
