Tor Lillqvist 97a18768d7 Avoid using only "real" paths for the tmpfont thing
If I have used a path with symlinks in it when changing directory to
my build directory, what gets put in config.status as ac_pwd is that
path, not a realpath version. That then propagates to
ac_abs_to_builddir and to SYSTEMPLATE_PATH, which is what Makefile.am
passes for the --o:sys_template_path option to coolwsd.

To be on the safe side, do the tmpfonts dance both for the systemplate
path that might include symlinks and for one that has been realpathed.
