Rename pg_regress option --multibyte to --encoding

Also refactor things a little bit so that the same methods for setting
test locale and encoding can be used everywhere.

     You can also choose the database encoding explicitly by setting
-    the variable <envar>MULTIBYTE</envar>, for example:
+    the variable <envar>ENCODING</envar>, for example:
 <screen>
-gmake check LANG=C MULTIBYTE=EUC_JP
+gmake check LANG=C ENCODING=EUC_JP
 </screen>
     Setting the database encoding this way typically only makes sense
     if the locale is C; otherwise the encoding is chosen automatically
