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. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
