lib: add igt_dummyload

A lot of igt testcases need some GPU workload to make sure a race
window is big enough. Unfortunately having a fixed amount of
workload leads to spurious test failures or overly long runtimes
on some fast/slow platforms. This library contains functionality
to submit GPU workloads that should consume exactly a specific
amount of time.

Since v14: Since we are using multiple signals, walk list of batches
to terminate a batch to avoid using a single global batch. Cycle signals
between SIGRTMIN and SIGRTMAX properly.
