configure.ac: Increase pango minimum version from 1.20 to 1.22

Commit bd4d6e7453 (cairo: Avoid deprecated
pango_cairo_font_map_create_context().) added a dependency on pango
version 1.22 or later, but configure.ac only checked for version 1.20
or later.  This commit fixes the discrepancy.

INSTALL already documented that Pango 1.22 or later was needed.
