fs_mgr: overlayfs support legacy devices (marlin)
Expand the tests to deal with the boot environment for marlin.
Recognize that older overlayfs drivers do not report to /sys/module
and the parsing /proc/filesystem is another place to interrogate this.
Suppress adb push and pull noise during testing. Resolve APEX
failures. Add some cleanup to test script.
NB: Running test to completion is difficult because marlin's USB
driver is flakey enough through the multitude of reboots and
may not reconnect. The tester will have to notice when a reboot
is stalling and manually disconnect and reconnect the USB
connection to trigger discovery and to continue through the
test sequences. To make this easier, report when we are
waiting for the device to make it easier to babysit.
