pg_resetwal's custom logic to retrieve the version number of a data
folder's PG_VERSION can be replaced by the facility introduced in
cd0be131ba. This removes some code.
One thing specific to pg_resetwal is that the first line of PG_VERSION
is read and reported in the error report generated when the major
version read does not match with the version pg_resetwal has been
compiled with. The new logic preserves this property, without changes
to neither the error message nor the data used in the error report.
Note that as a chdir() is done within the data folder before checking the
data of PG_VERSION, get_pg_version() needs to be tweaked to look for
PG_VERSION in the current folder.
