package/owfs: fix link with FUSE

owfs reinvents its own weird and wicked mechanism to find libfuse. It
believes that, by default, FUSE is installed in /usr/local, and forcibly
uses that path to look for headers and libs.

This is obviously wrong in cross-compilation, and triggers our check for
unsafe header/library paths.

The best option to fix that would be to use pkg-config to find FUSE, but
this is a bit involved. Instead, use config options to specify the path
to the headers and libs.

Fixes:

    and a few others...
