[PATCH] gc: remove unused launchctl_get_uid() call

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

When the launchctl_boot_plist() function was added in
a16eb6b1ff3 (maintenance: skip bootout/bootstrap when plist is
registered, 2021-08-24), an unused call to launchctl_get_uid() was
added along with it. That call appears to have been copy/pasted from
launchctl_boot_plist().

Since we can remove that, we can also get rid of the "result"
variable, whose only purpose was allow for the free() between its
assignment and the return. That pattern also appears to have been
copy/pasted from launchctl_boot_plist().

I happen to have a local topic that refactored the launchctl_get_uid()
function away, that didn't compile with the updated "master", I
figured I'd need to add it back since it had a new user, but as it
turns out that hopefully won't be needed.
