tests: configure fsmonitor.mode=paranoid always if fsmonitor is used
This forces fsmonitor extension execute "paranoid" code path.
Strict speaking, we should make fsmonitor-run-tests.py accept own
specific options, but there is no code path, which is disabled in
"paranoid" mode, at least now. Therefore, this solution seems
reasonable enough.
#require execbit
$ hg init
$ echo a > a
$ hg ci -Am'not executable'
adding a
$ chmod +x a
$ hg ci -m'executable'
$ hg id

Make sure we notice the change of mode if the cached size == -1:
$ hg rm a
$ hg revert -r 0 a
$ hg debugstate
n 0 -1 unset a
$ hg status
M a
$ hg up 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved

$ test -x a && echo executable -- bad || echo not executable -- good
not executable -- good
