Fixes <https://bugs.gnu.org/42129>.
* etc/guix-install.sh (sys_create_build_user): If a 'kvm' group exists,
add it to the guixbuilders' lists of supplementary groups.
With zero context new definitions would be applied to the wrong location in
the file. More context lines lead to larger hunks, though, so we use just one
line of context.
* etc/committer.scm.in (diff-info): Invoke "git diff" with one line of
context.
[info]: Merge line break and first line.
(lines-to-first-change): New procedure.
(old-sexp, new-sexp): Use it.
* etc/committer.scm.in (<hunk>)[diff]: Rename this field...
[diff-lines]: ...to this.
[definition?]: New field.
(hunk->patch): Join diff lines.
(diff-info): Do not join diff lines; record whether a hunk is a new
definition.
(commit-message): Rename this procedure...
(change-commit-message): ...to this.
(add-commit-message): New procedure.
(main): Handle new package definitions before changes.

After initial installation on a foreign distro, the guix pull profile
won't be present in path. This means that the first guix pull won't take
effect until the shell is restarted.
~/.guix-profile cannot be pre-loaded like this as the relevant paths are
stored in ~/.guix-profile/etc/profile, which simply won't exist.
However, guix package will output a relevant hint that instructs the
user to reload the profile, so this isn't a problem.
