Adds the necessary data dependencies for Telemetry ChromeOS stack
symbolization to work on the bots and re-enables the stack symbolization
tests on ChromeOS.

Also adds support for ChromeOS to generage_breakpad_symbols.py, which is
the same as Android. This is necessary because Android and ChromeOS need
to use readelf instead of ldd due to potentially different architectures
between the host and device.
