pgsql: Simplify matching pattern check in TAP tests of pg_receivewal

Simplify matching pattern check in TAP tests of pg_receivewal

A check in the ZLIB portion of the test to match the name of a
non-compressed partial segment with a completed compressed segment was
using m//, while a simple equality check is enough.  This makes the test
a bit stricter without impacting its coverage.
