tests/acceptance/virtiofs_submounts: standardize port as integer
Instead of having to cast it whenever it's going to be used, let's
standardize it as an integer, which is the data type that will be
used most often.
Given that the regex will only match digits, it's safe that we'll
end up getting a integer, but, it could as well be a zero.
