[oe] [RFC] Remove older freetype versions

[Tom Rini]

Hey all,

I'd like to remove all versions of freetype before 2.4.3.  The only dist 
which is pinning freetype currently does so via
conf/distro/include/preferred-opie-versions.inc and that pins to a 
non-existent version (it's using OPIE_VERSION which seems wrong).  All 
of the previous versions have various security issues, including 
remotely exploitable ones.  Only the very oldest version we have as a 
D_P -1 so everyone was using 2.3.12 and will be going up to 2.4.3 
(libraries are compat).
