If Doom doesn't live in ~/.emacs.d or ~/.config/emacs, then it cannot
play the role of bootloader, so opt out of generating the profile
bootstrappper in this case.
That said, don't disable the profile system entirely; it can still be
useful for internal, noninteractive, and sandbox use.
I forgot to add the definitions for the 'doom profile{s,}' commands in
b914830, which causes "unrecognized command 'profiles sync'" errors on
'doom {sync,upgrade}'.
My unparalleled brilliance is 4 parallel universes ahead of me, clearly.
