[igt-dev] [PATCH i-g-t 1/7] Remove parameter aliases with another argument

[Rodrigo Siqueira]

This commit fixes the following GCC warning:

warning: passing argument 2 to restrict-qualified parameter aliases with
argument 1 [-Wrestrict]
  return (readlink (buf, buf, sizeof (buf)) != -1 &&

This commit fixes the GCC warning by creating a second buffer only to
keep the path.
