[meta-java][PATCH] openjdk-7: ignore the readdir_r deprecation already ignored in openjdk-8

[Cody P Schafer <dev@codyps.com>]

Without this, icedtea7-native (used to bootstrap openjdk) fails to build on my
host system due to deprecation warnings being treated as errors.

I haven't observed the same issue with openjdk-7 itself, but it seems likely to
affect it as well, so I've added the -Wno-error flag there too.
