test-memcpy-support.h: Double TIMEOUT to (16 * 60)

  On Ice Lake and Tiger Lake laptops, test-memcpy and test-mempcpy timeout
when there are 3 "make check -j8" runs in parallel. Double TIMEOUT to
(16 * 60) to avoid timeout.

Shouldn't you be using TIMEOUTFACTOR if running the test suite in
parallel?  There are likely other issues as well.

Thanks,

I prefer a configure option over an environment variable.  I'd like to
add --with-timeoutfactor=.

Maybe instead of increasing the timeout we should make the extra memcpy
tests only run if explicitly set to. We only really need the run them
when making
changes to memcpy, otherwise its basically adding several minutes to the test
time.

I think we should always run all tests.  I am working on the v2 patch to add
--with-timeoutfactor=NUM to specify an integer to scale the timeout.
