Repositories with less than 4000 entries are always handled using a
single thread, causing test-lazy-init-name-hash --multi to error out.
Don't abort the whole test script in that case, but simply skip the
multi-threaded performance check. We can still use it to compare the
single-threaded speed of different versions in that case.

If the single-threaded variant beats the multi-threaded one then we may
have a performance bug, but that doesn't justify aborting the test.
Drop that check; we can compare the results for --single and --multi
using the actual performance tests.

The perf test suite (more specifically: t/perf/aggregate.perl) requires
each test script to write test results into a file, otherwise it aborts
when aggregating. Add actual performance tests with test_perf to allow
p0004 to be run together with other perf scripts.
Calibrate the value for the parameter --count based on the size of the
test repository, in order to get meaningful results with smaller repos
yet still be able to finish the script against huge ones without having
to wait for hours.

The return code of commands on the producing end of a pipe is ignored.
Evaluate the outcome of test-lazy-init-name-hash by calling sort
separately.

The test library puts helpers into $PATH, so we can simply call them
without specifying their location.
The suffix $X is also not necessary because .exe files on Windows can be
started without specifying their extension, and on other platforms it's
empty anyway.

It looks like in 89c3b0ad43 (name-hash: add perf test for lazy_init_name_hash,
2017-03-23) p0004 was not created with the execute unix rights.
Let's fix that.

Created t/perf/p0004-lazy-init-name-hash.sh test
to demonstrate correctness and performance gains
with the multithreaded version of lazy_init_name_hash().
