lib/igt_core: Add igt_system helpers

Support executing external processes with the goal of capturing its
standard streams to the igt logging infrastructure in addition to its
exit status.

v3: Rename igt_exec -> igt_system (Chris).

v2: Fix leaks on fd teardown. Make sure redirected process printout when
    > 64kb still works, like full dmesg. (Petri).
