fuse: Fix installed-vs-shipped for nativesdk

There are two problems:
* The /dev is installed to '${D}/dev', not '${D}${base_prefix}'
* The /etc is installed ${D}, but should be ${D}${sysconfdir}

It works for target is because target's base_prefix is NULL, but it isn't work
for native or nativesdk.

Fixed:
$ bitbake nativesdk-fuse
