pgsql: (Blindly) tweak new test regex

(Blindly) tweak new test regex

gcc-based Windows buildfarm animals are not happy about a multiline
regular expression I added recently. Try to accomodate; existing
pg_basebackup tests suggest that \n should work instead of a bare
newline, but throw in \r also. This being perl, TIMTOWTDI.
Also remove the pointless $ at the end of the pattern, for extra luck.

(If this doesn't work, I'll probably just split the regex in two.)

Per buildfarm members jacana and fairywren.
