BATS: fix corner case in --userns=keep-id test
The test that does 'adduser' in a keep-id container had a
really dumb bug: if the user running the test has UID 1000,
then podman itself (via keep-id) will add the "1000" passwd
entry, and the in-container "adduser" will allocate 1001,
making our test fail. This triggered in f31/f32 podman gating
tests, but (?!?) never in rawhide gating tests.
Solution: explicitly feed a UID to adduser. Make sure that
it's not the same as the UID of the current user.
Also (unrelated): fix a ridiculous "run mkdir || die". At
the time I wrote that I probably had no idea how BATS works.
