lib: Fix reading FUSE output on Raspbian

The previous patch only fixed listing the contents on the fuse
filesystem. Apparently files with st_blocks = 0 as seen as empty on
Raspbian, and the FUSE read() function isn't invoked for such
files. Setting st_blocks to 1 fixes that, but st_blksize is ignored
for fuse. So, on raspbian the filesize is now a huge number, but at
least reading the fuse filesystem works.

Corrected the filesystem attributes for the IPCP output for systems
that don't rely on st_blocks to assess filesize.

Also set the file mode to 0644 as these are not executables.
