Always build a handful of edge-case WebRTC targets.

We don't run tests on frame_analyzer or remoting/webapp, but we have
found we should build them. The former checks our quality toolchain
builds in chromium, and remoting/webapp builds WebRTC through the
extremely strange pnacl build process.

I reckoned the regular builders should build those, otherwise regular
compile failures in the two above components look like dbg-only
failures, which is misleading. The bots will compute what other
binaries they need based off what the triggered tester is using.
