Work around a bug in gyp triggered by webkit_appcache.gypi.

The bug seems to be showing up on the chromium build.webkit.org bots
where we're generating two different versions of webkit_appcache.target.mk
and the second one is overwriting the first, but is being considered
to not be "part of all". As a result, DumpRenderTree is no longer being
built by "make all".
