malloc: Decrease resource usage for malloc tests
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.
