pgsql: Revert "Rename contrib module basic_archive to basic_wal_module"

Revert "Rename contrib module basic_archive to basic_wal_module"

This reverts commit 0ad3c60, as per feedback from Tom Lane, Robert Haas
and Andres Freund. The new name used for the module had little
support.

This moves back to basic_archive as module name, and we will likely use
that as template for recovery modules, as well.
