[oe] [meta-java][PATCH 2/3] Avoid parse time erros due to dependency on x11, for distros without x11

[Mario Domenech Goulart]

BitBake raises some errors when processing recipes that depend on x11
for distros that don't have x11 in DISTRO_FEATURES. To work around
that issue, REQUIRED_DISTRO_FEATURES = "x11" (from
distro_features_check.bbclass) has been set for the following recipes:

* cacao
* classpath
* jamvm
* openjdk-6-release
* openjdk-7-release

That makes BitBake skip those recipes during the cache generation
(they'd still be parsed, but ignored).
