fix build: Revert "Add myself to the maintainers file"

This reverts commit 4c0c1016936977ed6b68c55fbc27e7cc34fa5ea9.

The contents of MAINTAINER is slurped into the Makefile, where a
variable is assigned the result.

A multi-line MAINTAINER file results in:
	Makefile:254: *** missing separator.  Stop.
