commit_ts and test_pg_dump were declaring targets before including the
PGXS stanza, which meant that the "all" target customarily defined as
the first (and therefore default target) was not the default anymore.
Fix that by moving those target definitions to after PGXS.
commit_ts was initially good, but I broke it in commit 9def031bd2;
test_pg_dump was born broken, probably copying from commit_ts' mistake.
In passing, fix a comment mistake in test_pg_dump/Makefile.
Backpatch to 9.6.

These tests verify that 1) WAL replay preserves the stored value,
2) a streaming standby server replays the value obtained from the
master, and 3) the behavior is sensible in the face of repeated
configuration changes.
One annoyance is that tmp_check/ subdir from the TAP tests is clobbered
when the pg_regress test runs in the same subdirectory. This is
bothersome but not too terrible a problem, since the pg_regress test is
not run anyway if the TAP tests fail (unless "make -k" is used).
I had these tests around since commit 69e7235c93e2; add them now that we
have the recovery test framework in place.
Transactions can now set their commit timestamp directly as they commit,
or an external transaction commit timestamp can be fed from an outside
system using the new function TransactionTreeSetCommitTsData(). This
data is crash-safe, and truncated at Xid freeze point, same as pg_clog.
This module is disabled by default because it causes a performance hit,
but can be enabled in postgresql.conf requiring only a server restart.
A new test in src/test/modules is included.
Catalog version bumped due to the new subdirectory within PGDATA and a
couple of new SQL functions.
