When invoked directly (rather than via 'make check'), runtests.py
previously left the user with a wall of confusing "not found" errors
from inside individual test scripts if the CHECK_PROGS helpers had not
been built. Detect this up front and point the user at the make
target that builds them.

The sorted() call reordered skipped test names alphabetically,
causing CI expected-skipped mismatches (e.g. acls,acls-default
instead of acls-default,acls). Sort by original test order instead.

Add parallel test execution using concurrent.futures. With -j8 the
test suite completes in ~4s vs ~29s sequential (~7x speedup).
Also fix two issues that caused failures under parallel execution:
- rsync_ls_lR now prunes testtmp/ so parallel tests don't see each
other's temp files when scanning the source tree
- clean-fname-underflow.test now uses $scratchdir instead of /tmp

Rewrite the test runner in Python with proper command-line options
including --valgrind which directs valgrind output to per-process
log files so it doesn't interfere with test output comparisons.
