Add Erase verifyGeometry
This confirms specified amount of the drive is accessible. The min and
max expected drive size are set as a build configuration, and compared
against the drive size (found by using the linux ioctl). Also adds
testing build files, testing options, and verifyGeometry test.
Tested: Ran eStoraged on a machine with an eMMC, using the following
$ ./eStoraged -b /dev/mmcblk0 &
$ busctl call xyz.openbmc_project.eStoraged.mmcblk0 \
/xyz/openbmc_project/storage/mmcblk0 \
xyz.openbmc_project.eStoraged Erase ays 1 1 \
xyz.openbmc_project.eStoraged.EraseMethod.VerifyGeometry
