testsuite: minor w32 fixes.

[Ralf Wildenhues]

A complete testsuite run on Cygwin (thanks Bruno!) uncovered a couple
more w32-related test failures.  The parallel-tests3.test actually
needed another $sleep, so I figured we might as well wait until the
test log summary has been written, and then just a bit longer so that
'make' has enough time to also exit.

Pushed to master.

Cheers,
Ralf

    testsuite: minor w32 fixes.
    
    * tests/depend5.test: Don't fail if the system or file system
    cannot handle weird characters, instead just try a few.
    * tests/parallel-tests3.test: Really wait until the serial test
    has finished, before letting the cleanup trap do its work.
