build: resolve lex failure

This is an addendum to 0a9d5fcfa4c3fe8c930103f7639723dfd1ae4889,
which forgot to change ${LEX} to ${FLEX} in lib/Makefile.am.

On openSUSE, /usr/bin/lex is a wrapper that calls `flex -l ...`.
libnl however requires flex, not lex or a compat mode thereof,
so using ${FLEX} is the proper thing to do.
