Move psql's psqlscan.l into src/fe_utils.

Browse Source 
This completes (at least for now) the project of getting rid of ad-hoc
linkages among the src/bin/ subdirectories.  Everything they share is now
in src/fe_utils/ and is included from a static library at link time.

A side benefit is that we can restore the FLEX_NO_BACKUP check for
psqlscanslash.l.  We might need to think of another way to do that check
if we ever need to build two lexers with that property in the same source
directory, but there's no foreseeable reason to need that.
