Change interface for providing files to Minidump (#19). r=bryner
- Interface change: Minidump constructor now accepts a const string& path
argument instead of int fd. Minidump will open the file on first Read
and close it upon destruction.
- Adapt callers to new interface, no longer leaking file descriptors.
