MAINTAINERS: Updating after change to tools/include/

The LIBS section doesn't mention the headers associated with the
libraries, same for LIBXENLIGHT section.

They aren't any ':' in other section names, so remove it.

Fixes: 4664034cdc ("tools/libs: move official headers to common directory")
Fixes: f7079d7ef6 ("MAINTAINERS: add myself as tools/libs reviewer")
