[PATCH RFC] tools/nolibc: Add gitignore to avoid git complaints about sysroot

[Paul E. McKenney]

Testing of nolibc can produce a tools/include/nolibc/sysroot file, which
is not known to git.  Because it is automatically generated, there is no
reason for it to be known to git.  Therefore, add a .gitignore to remove
it from git's field of view.
