[OE-core] [PATCH] directfb: Improve CFLAGS handling for x86

[Richard Purdie]

The problem with filter_out is that it expands the variable meaning overrides
to sub components can get lost. This has happening to the security flags
meaning directfb failed in lsb builds.

Use _remove instead of filter_out since it gives much more predictable results.
