WUtil: mark the script 'get-wutil-flags' as deprecated

This script should have been removed a long time ago, in favour of
pkg-config which has to be present anyway to compile Window Maker.

This patch makes the script print a warning about it, and now calls itself
pkg-config, instead of being generated; the man page was also updated
accordingly (and spell-checked).

+As with every deprecated stuff, the script \fBget-wutil-flags\fR will be removed soon,
