[PATCH i-g-t] intel_reg: Stop warning if register spec is not there

[Lucas De Marchi]

Stop suffering when using igt from the git checkout, which is the case
for all/most developers.

	$ sudo ./build/tools/intel_reg write 0x2358 0xdeadbeef
	Warning: stat '/usr/local/share/igt-gpu-tools/registers' failed: No such file or directory. Using builtin register spec.

Pretty annoying when you have a bunch of commands to run and don't want
to simply ignore stderr.  Keep the other warnings as if the file is
there and can't be read for some reason, it's good to give a warning.
However if the file simply isn't there, let it pass.
