Bug 1577411 - Don't build breakpad host tools on Windows host when building GeckoView. r=firefox-build-system-reviewers,chmanchester

Bug 1558372 allows to build crash reporter for Android even if host isn't
Linux. But when using Windows host, it is still broken.

Host libraries and tools in `toolkit/crashreporter/google-breakpad/src/common`
is only for Linux host and macOS host. So if using Windows host, it isn't
buildable.  So I would like to exclude this if host is windows.

Also, `toolkit/crashreporter/google-breakpad/src/tools/linux/dump_syms` is
only for Linux host.
