Thomas Munro 852de579a6 Fix pg_waldump/t/001_basic.pl with BSD tar on ZFS. 
The new test fails with an error about a missing WAL file on that
stack, because it is archived in GNU tar's --sparse --format=posix
format.  BSD tar uses that format by default, unlike GNU tar itself, and
ZFS triggers it by implicitly creating sparse files when it sees a lot
of zeroes.

The problem will surely also affect real users of the new tar support in
pg_waldump (commit b15c1513) and pg_verifybackup (commit b3cf461b3) on
such systems.  Ideas under discussion, but for now the test is made to
pass by disabling sparse file detection in BSD tar.
