tst_test: Allow to set timeout from test setup()
There are testcases that take runtime as a parameter. These needs to be
able to set the timeout dynamically in the test setup().
This commit places the timeout value into the struct results stored in
shared memory so that it can be changed from the test setup() that runs
in the child process.
We also add tst_set_timeout() helper function that stores the value and
also sends heartbeat (SIGUSR1) so that the new value is used
immediately.
+ Added a few lines about test timeouts into the documentation.
