libchromeos: Add error location informaion to chromeos::Error

The error information logged always appears to come from error.cc
file in libchormeos since that's where LOG(ERROR) statement is.

Added the ability to pass in the actual source of the error by
using tracked_objects::Location parameter and "FROM_HERE" macros
used in base::TaskRunner-based classes.

While all the system log messages looked like this:

[ERROR:error.cc(15)] Domain=peerd, Code=service.info, Message=Invalid service key.

Now they appear as this:

ERROR:service.cc(155)] IsValidServiceInfo(...): Domain=peerd, Code=service.info, Message=Invalid service key.

We report the actual source file and line number where the error is
coming from, as well as the function name.

BUG=None
