Subject: [PATCH 1/2] cmake: lemon: fix path to internal lemon tool

Wireshark fails to build on my Gentoo/ChromeOS systems
because the lemon command is not  properly specified or
included in PATH, failing with:

/bin/sh: lemon: command not found

The relevant excerpt from build.ninja is:

COMMAND = cd ..._build/plugins/epan/mate && lemon -T.../tools/lemon/lempar.c
-d. .../plugins/epan/mate/mate_grammar.lemon

By specifying the full path to "lemon" we ensure it is
always searched for and found in the correct location.
