util/kconfig: Add pre-built parser

It avoids the dependency on bison/flex, minimally speeds up the build
and also works around weird race conditions in some versions of bison
that need more investigation.

The issue this avoids manifests as a build error when creating
parser.tab.c:

    input in flex scanner failed
    make: *** [util/kconfig/Makefile.inc:66: build/util/kconfig/parser.tab.c] Error 2

Since the error happens within bison the alternative would be to make
bison part of our crossgcc environment to ensure that no broken OS
build is used.

BUG=b:197515860
TEST=things build with bison not installed
