Let's make the code shorter, this avoid crashes (when drmModeGetCrtc()
fails) by using a couple of helpers. As get_resources() considers the
drmModeGetCrtc() fail non-fatal, we might as well handle it properly.

Flesh out the bo_create + drmModeAddFB2 dance into a helper and use it.

Freedreno uses VALGRIND_ENABLE_ADDR_ERROR_REPORTING_IN_RANGE that was
introduced in Valgrind 3.10.0
Raspbian Buster includes Valgrind 3.7.0, so when valgrind is installed
as freedreno is build by default the build becomes broken. So lets

Currently the code expects that the device found at
/sys/char/$maj:$min/device for USB devices is a "usb_device". However,
at least for some devices, such as for the udl driver, they are instead
a "usb_interface".
A usb_interface is a child of the usb_device we're interested in, so we
walk up one in the /sys path to get there.
For example, with a USB device I have, trimmed to show the relevant

Mesa expects to be able to map the same buffer, without unmapping it.
This leads to problem on long-running program.
On the other hand, libdrm uses cpu_map_count as a refcount and expects
its value to decrease so it can unmap buffers.
The previoulsy proprosed fix (https://patchwork.freedesktop.org/patch/258005/)
stopped increased the counter when it went past INT_MAX.
This commit instead proposes to use a larger type to store cpu_map_count.
The outcome is the same: long running apps will not crash, only the
implementation differs.

This test takes minutes to run, while all the other tests combined take
barely more than a second.
Dropping it also helps the CI by avoiding random timeouts when `random`
