pgsql: Fix parsing of xlog file name in pg_receivexlog.

Fix parsing of xlog file name in pg_receivexlog.

The parsing of WAL filenames of segments larger than > 255 was broken,
making pg_receivexlog unable to restart streaming after stopping it.

The bug was introduced by the changes in 9.3 to represent WAL segment number
as a 64-bit integer instead of two ints, log and seg. To fix, replace the
plain sscanf call with XLogFromFileName macro, which does the conversion
from log+seg to a 64-bit integer correcly.
