Subject: [PATCH] Dracut: handle not having a boot target

Code to detect the sysfs attribute "is_boot_target" was
failing in the case there was no such attribute, with
"is_boot" being set to some error message, rather than
the boolean "0" or "1" expected, causing calls to dracut
to rebuild the initramfs spew error messages when
detecting an iscsi root.
