test: canonicalize argv[0] in exepath test

Commit ff29322b ("test: canonicalize test runner path") from 2014
changed the test runner to call `realpath(3)` on `argv[0]` in order
to fix the `get_currentexe` test failing with the autotools build when
the executable path contained symbolic links but that is now causing
the `spawn_reads_child_path` test to fail on z/os with the cmake build.

Fix that by only doing path canonicalization in the `get_currentexe`
test, not always.

An auxiliary fix is applied to the `process_title_threadsafe` test
because it assumed that setting the process title to a long string,
then reading it back produces in the original string.

On some platforms however the maximum size of the process title is
limited to the size of the `argv` vector.

Because the test runner used absolute paths until now, the argv vector
was bigger than it is with relative paths, big enough to let this bad
assumption go unnoticed until now.

Minor fixes are applied to tests that assumed 1024 for the maximum
path size because this commit makes visible that some of the CI matrix
systems support much longer paths.

Back in the day I wrote comments in a really unusual way. Nowadays it
makes my eyes bleed, and clang-format doesn't know how to deal with it.

test: support flexibly setting custom task options

Add a single TEST_ENTRY_CUSTOM hook that can be used to override task
entry defaults. Different tests can have different timeouts depending on
what is appropriate for each test. A separate TEST_OUTPUT_ENTRY hook is
no longer necessary.

In order to support per-task timeouts, the timeout field has been moved
into the task_entry_t struct. The default (5000) is now set as part of
TEST_ENTRY.

The first form also isn't strictly conforming ANSI/ISO C.
