[PATCH] MAINTAINERS: exclude uapi directories in API/ABI section

Commit 7b4693e644cb ("MAINTAINERS: add uapi directories to API/ABI section")
added include/uapi/ and arch/*/include/uapi/ so that patches modifying them
CC linux-api. However that was already done in the past and resulted in too
much noise and thus later removed, as explained in b14fd334ff3d ("MAINTAINERS:
trim the file triggers for ABI/API")

To prevent another round of addition and removal in the future, change the
entries to X: (explicit exclusion) for documentation purposes, although they
are not subdirectories of broader included directories, as there is apparently
no defined way to add plain comments in subsystem sections.
