Breakpad: Avoid using the C++ <cfoo> headers.

This patch avoids unnecessary use of the <cfoo> headers in files that don't
actually use the identifiers they declare in the std:: namespace.

It also changes some files to better conform with the "Names and Order of
Includes" rules in the Google C++ Style Guide.
