Add regex library check and flags

Fossil-ID: SVN r2667
Checking whether or not we should use the 'regex' library... 

...should be done for all USB connected devices (since we use this in
the matcher function). In that case it is much cleaner to add this
check in nut_check_libusb.m4. This also fixes the wrong use of
AC_SEARCH_LIBS, that already adds '-lregex' to LIBS (which means all
binaries are linked against this library).
