Dreport: Add Mount Information File Collection
Add functionality to collect system mount information as part of the
debug data collection process. The mount info file contains details
about all mounted filesystems including mount points, filesystem
types, and mount options.
Including mount information in debug reports will help with
troubleshooting filesystem and storage related issues in OpenBMC
based systems by providing a snapshot of the system's mount
configuration at the time of report generation.
Tested on the qemuarm platform.
