malloc: Decrease resource usage for malloc tests

Browse Source 
The tst-mallocfork2 and tst-mallocfork3 create large number of
subprocesss, around 11k for former and 20k for latter, to check
for malloc async-signal-safeness on both fork and _Fork.  However
they do not really exercise allocation patterns different than
other tests fro malloc itself, and the spawned process just exit
without any extra computation.

The tst-malloc-tcache-leak is similar, but creates 100k threads
and already checks the resulting with mallinfo.

These tests are also very sensitive to system load (since they
estresss heavy the kernel resource allocation), and adding them
on THP tunable and mcheck tests increase the pressure even more.

For THP the fork tests do not add any more coverage than other
tests.  The mcheck is also not enable for tst-malloc-tcache-leak.

Checked on x86_64-linux-gnu.
