tests: make output lines conditional for testing with fsmonitor

Repository cloned-bookmark-default and tobundle exist in the working
directory of main test repository "repo". We should take care for
them, because it is known issue that fsmonitor can't handle nested
repositories.

These nested repositories are cloned from "repo", and the number of
unknown files = files in these repositories (including files under
.hg) will be changed easily in the future. But testing with fsmonitor
is not ordinary.

Therefore, test-bookmarks.t with fsmonitor might be broken silently.

This is reason why this patch uses "(glob)" for the number of unknown
files in "hg summary" output.

BTW, this patch doesn't use .hgignore to make test portable, because
.hgignore might cause another issue related to "walk_on_invalidate"
configuration of fsmonitor.
