[PATCH] generic/317: use id to get user id

[Eryu Guan <eguan@redhat.com>]

Greping username "fsgqa" in passwd file to get user id doesn't
always work, because the given username could match multiple
entries, e.g. when we have user "123456-fsgqa" (used by other tests)
in passwd file.

Fix it by using "id -u $qa_user" to get the user id directly.
