[oe] [meta-java][PATCH] java-library.bbclass: compatibility with per-recipe sysroots

[S. Lockwood-Childs]

The removebinaries task was intended to remove pre-built .jar and .class files
from the unpacked source, but when per-recipe sysroots were implemented and
ended up under WORKDIR, .jar or .class in those sysroots inadvertently started 
getting killed as well.

For instance, ${WORKDIR}/recipe-sysroot-native/usr/share/java/ecj-bootstrap.jar
was deleted when attempting to build jlex-native... which made javac in
that sysroot rather unhappy.

Solve by excluding both recipe-sysroot and recipe-sysroot-native dirs
from the search-and-destroy operation.
