Subject: e2fsdroid and mke2fs are dynamic executable in recovery partition

The two utilities are now converted to dynamic executables as shared
libraries are supported in recovery mode.

As part of the conversion, their location has moved from /sbin to
/system/bin. Reflect the change in the program 'recovery'

Bug: 79146551
Test: adb reboot recovery, and select 'Wipe data/factory reset'. The
data partition is formatted and there is no selinux denial.
