Maximiliano Sandoval fcccc3dfa5 fix #3699: client: prefer xdg cache directory for tmp files ...

Adds a helper to create temporal files in XDG_CACHE_HOME. If we cannot
create a file there, we fallback to /tmp as before.

Note that the temporary files stored by the client might grow
arbitrarily in size, making XDG_RUNTIME_DIR a less desirable option.
Citing the Arch wiki [1]:

> Should not store large files as it may be mounted as a tmpfs.

While the cache directory is most often not backed up by an ephemeral
FS, using the `O_TMPFILE` flag avoids the need for potential cleanup,
e.g. on interruption of a command. As with this flag set the data will
be discarded when the last file descriptor is closed.
