Use find-headers instead of find-files to detect builtin header files.

- honour cache directive from FUSE filesystem for name and attrbiutes

Log message:
Update perfused:

Log message:
perfuse update: Fix permissions sent to FUSE when operations are done by
the kernel

Log message:
Update perfuse to fix a race condition between ftruncate() and write()
on glusterfs. This caused random file chunks to be filled with zeros.

Log message:
Make patch apply.

Log message:
Make sure libperfuse has -lpuffs, so that DSO will not miss it when
calling dlopen()

Log message:
Reduce context so $NetBSD$ inside the file-to-be-patched isn't in the patch.
