guix package: Make custom profiles actual indirect roots.
Before that, any profile generation built when '-p' is used would effectively become a permanent GC root because the symlink in /var/guix/gcroots/auto would point directly to /gnu/store/...-profile. * guix/scripts/package.scm (maybe-register-gc-root): Rename to... (register-gc-root): ... this. Remove conditional, and replace call to 'canonicalize-path' with (string-append (getcwd) "/" ...). (guix-package): Call 'register-gc-root' only if PROFILE is different from %CURRENT-PROFILE. * tests/guix-package.sh: Add test case.
