environment: Add --link-profile.
This change is motivated by attempts to run programs (like GNU IceCat) within
containers. The 'fontconfig' program, for example, is configured explicitly
to check ~/.guix-profile for additional fonts.
There were no existing container tests in 'tests/guix-environment.sh', but I
added one anyway for this change.
* doc/guix.texi (Invoking guix environment): Add '--link-profile'.
* guix/scripts/environment.scm (show-help): Add '--link-profile'.
(%options): Add 'link-profile' as '#\P', assigned to 'link-profile?'.
(link-environment): New procedure.
(launch-environment/container): Use it when 'link-profile?'.
[link-profile?]: New parameter.
(guix-environment): Leave when '--link-prof' but not '--container'. Add
'#:link-profile?' argument to 'launch-environment/container' application.
* tests/guix-environment-container.sh: New '--link-profile' test.
