base-files: add filter to ignore mmc RPMB partitions 

The Replay Protected Memory Block (RPMB) is an special storage
partition that cannot be accessed via standard block layer.
When a user space tool like blkid, tries to read it the kernel
suffers buffer I/O errors and timeouts.

This commit modifies the post installation script to filter the RPMB
partitions from the mmc block devices, to avoid multiple kernel
errors during the script execution.
