In the general case ostree wants to support using fd-relative paths, so we need to open a fd for the dir (relative to self->sysroot_fd), then use fgetxattr().

Also
g_autofree int len
Definitely don't want to call free() on an integer. Also, getxattr returns a ssize_t, not an int (they're different sizes).

New API needs to be added to libostree-devel.sym; there's some ceremony to do that. See the comments around that and git log.
This is a Work in progress and is very bad atm, still need to re-work it with GVariant and test it, but it builds locally... somehow.
