templater: evaluate each item of revset() as integer revision

Because templater.revset() returns a list of strings, repo["-1"] was mapped to
the tipmost revision. Ideally, we should make revset() return a list of integer
revisions, but it turned out not simple. If revset() is a list of integers,
"{ifcontains(rev, revset(), ...)}" would fail because "ifcontains" casts "rev"
to a string.

So this patch just converts a string back to an integer revision.
