[PATCH v2 07/20] builtin/archive: fix leaking `OPT_FILENAME()` value

[Patrick Steinhardt <ps@pks.im>]

The "--output" switch is an `OPT_FILENAME()` option, which allocates
memory when specified by the user. But while we free the string when
executed without the "--remote" switch, we don't otherwise because we
return via a separate exit path that doesn't know to free it.

Fix this by creating a common exit path.
