[CI 1/6] lib/igt_drm_fdinfo: Fix wrong name len assert

[Lucas De Marchi <lucas.demarchi@intel.com>]

When parsing engine name, at this point we have something like:

	"drm-engine-render:	232409619162 ns"
	            ^      ^
	            |      |
	          name     p

We are copying the engine name to the final destination, but
strlen(name) will actually contain the entire string. Since we already
know the name length, calculated previously, just use it for copying the
string.

Since each name is 256-bytes long, the assert doesn't trigger easily,
but it's better to be correct. And more efficient.
