ueventd: add no_fnm_pathname option

If a `*` appears within (but not at the end) of a /dev or /sys path in
a ueventd.rc file, then that path is matched with fnmatch() using the
FNM_PATHNAME, which means `*` will not match `/`.  That is not always
the intended behavior and this change creates the no_fnm_pathname
option, which will not use the FNM_PATHNAME flag and will have `*`
match `/`.
