multiboot_select plugin check volume root for valid firmware -- Try 2

Browse source 
I'm not sure why but on my fuze v2 I don't get the '.' nd '..'
directories back from readdir

that make removing '.' to find /.rockbox inconsistent

Instead filter out files and strcmp the incoming dirs
to BOOTDIR (.rockbox) and clear it when they match
