correctly mount tmpfs as /tmp in recovery

The syntax of init's mount command changed in April 2008 but
recovery's init.rc was never updated, so recovery's /tmp has been on
the root fs all this time.  Fix.

Also add /system/bin to the PATH in recovery, which is handy for
debugging.

Fix /data backup size if contains media subdirs

/data/*/media directories are mistakenly being excluded from the size

excluded.

Remove deprecated tar exclude functionality

twrpDU::check_skip_dirs() handles skipped folders now. Everywhere
twrpTar::setexcl() is being used to exclude files eventually calls
createTarFork(), which in turn calls Generate_TarList(), which checks
check_skip_dirs().
