sci-libs/scotch: Add flex-2.6.3 compatibility patch

Flex-2.6.3 changed and is different from the behavior shown in 2.6.1 and
older.  The behaviorial differences prevent scotch from building with
2.6.3.  This patch adds code to detect 2.6.3 or newer and apply fixes
that correctly reflect the new flex behavior.

Package-Manager: Portage-2.3.3, Repoman-2.3.1
Closes: https://github.com/gentoo/gentoo/pull/3307
