Avoid using readlink(1) which is not POSIX-compatible; moreover,
`readlink -f` is not available on Mac OS by default.
Instead, always convert $CALCURSE to an absolute path (that may or may
not be canonical, i.e., be a symlink or contain ../ as component) in
test-init.sh by prepending the current working directory if the original
path is relative. While not fully equivalent to `readlink -f`, this
should be good enough for use in our tests.

Ensure that calcurse uses the right data and configuration directories
depending on the conditions.
