Wrapping fdopen() proved dangerous, the underlying fd is not refcounted,
and we must close it in the library or else we easily leak and exhaust
all fd. Since we can't provide igt_debugfs_fopen(), move the burden onto
the caller for those that require a stream FILE*.

This reverts commit 301ad44cdf1b868b1ab89096721da91fa8541fdc.
When a render-only device is opened and gem_quiescent_gpu is called, we
need to use the debugfs dir for the master device instead.

When opening a DRM debugfs file, locate the right path based on the
given DRM device FD.
This is needed so, in setups with more than one DRM device, any
operations on debugfs files affect the expected DRM device.
v2: - rebased and fixed new API additions
v3: - updated chamelium test, which was missed previously
- use the minor of the device for the debugfs path, not the major
- have a proper exit handler for calling igt_hpd_storm_reset with the
right device fd.
