generic/317: use id to get user id

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.
