pgsql: Make ECPG test programs depend on "ecpg$(X)", not "ecpg".

Make ECPG test programs depend on "ecpg$(X)", not "ecpg".

Cygwin builds require this of dependencies pertaining to pattern rules.
On Cygwin, stat("foo") in the absence of a file with that exact name can
locate foo.exe.  While GNU make uses stat() for dependencies of ordinary
rules, it uses readdir() to assess dependencies of pattern rules.
Therefore, a pattern rule dependency should match any underlying file
name exactly.  Back-patch to 9.4, where the dependency was introduced.
