*/*: [QA] Fix trivial cases of MissingTestRestrict

The result was achieved via the following pipeline:

    pkgcheck scan -c RestrictTestCheck -R FormatReporter \
      --format '{category}/{package}/{package}-{version}.ebuild' |
    xargs -n32 grep -L RESTRICT |
    xargs -n32 sed -i -e '/^IUSE=.*test/aRESTRICT="!test? ( test )"'

The resulting metadata was compared before and after the change.
Few Go ebuilds had to be fixed manually due to implicit RESTRICT=strip
added by the eclass.  Two ebuilds have to be fixed because of multiline
IUSE.
