Fix for Cannot load etc/recovery.fstab when doing OTA upgrade

1.In ANP, the path of the executable file recovery is sbin/recovery, and in ANR it is system/bin/recovery
2.Add a judgment on whether sbin/recovery exists in fs_mgr_fstab.cpp,
Make it possible to correctly load etc/recovery.fstab in recovery mode
