instead of using the lgetxattr and llistxattr system calls on the
entire file path, use the /proc/self/fd/$FD/$RELATIVE_PATH path
instead so that the lookup is relative to the lower dir file
descriptor that is already open.

Many distros package libfuse's versions as different packages. For
example, Ubuntu (jammy for example) has a package for libfuse2 and
libfuse3. Now the issue is that libfuse-dev pulls is libfuse2 while
there is no libfuse2-dev. This patch clarifies the version of fuse in
the configure error.

This happens to not be an issue with glibc because it gets indirectly
included via dirent.h:
.. /usr/include/dirent.h
[...]
..... /usr/include/linux/limits.h
When using the musl libc implementation, that is not the case anymore
and the build fails.

Set correct value of RENAME_NOREPLACE when RENAME_EXCHANGE is not

incorrect.
