base-files: fix checks done to execute resize2fs postinst function in kernel 5.4 

MMC core block has changed in kernel 5.4 so Replay Protected Memory Block (RPMB)
and boot partitions are not listed under /proc/partitions anymore.

get_emmc_block_device() function in pkg_postinst_ontarget() method was looking
for these entries to identify the MMC partition where to execute resize2fs.

This function has been modified to do the checks inside /dev/mmcblk* where RPMB
and boot entries are still listed.
