recipes-support: replace virtclass-native(sdk) with class-native(sdk)

The overrides virtclass-native and virtclass-nativesdk are deprecated,
which should be replaced by class-native and class-nativesdk.

NOTE:
There were 2 errors in libcap.inc, the BUILD_LDFLAGS_virtclass_native
should be BUILD_LDFLAGS_virtclass-native (the "_" should be "-"),
otherwise it doesn't work, and the value was: "-Wl,rpath=...", this is
incorrect, it shoudl be: "-Wl,-rpath=..." (lacked a - ), but we don't
need this line, since it is already in the default BUILD_LDFLAGS. Remove
it and we don't need to bump the PR since we just removed a unused line.

[YOCTO #3297]
