#3297: check_gdal regress fails if gdal_enabled_drivers already has drivers

 I thought I complained about this already, but can't find the ticket.

 Anyway on my windows box where I've got GDAL_DRIVERS set, check_gdal
 always fails.


 {{{
  check_gdal .. failed (diff expected obtained:
 /projects/postgis/tmp/2.2_pg9.4w64/test_1_diff)
 }}}


 On closer inspection, it seems the first test runs without setting
 drivers, and assumes the user is at the default state of -- no drivers and
 it also checks end state to assuming again user is running without
 drivers.  This of course is not true when I launch my instances with
 something like


 {{{
 @SET GDAL_DRIVERS=something
 }}}

 or have in postgresql conf to have this set.
