Support symlinks in the jd-cli wrapper

[cutephoton]

POSIX can be really limiting, eh? sigh I think readlink -e path might be a compromise since it's generally available. It's not shell specific. Do you see a better option?

Where does that script come from anyway? I don't see it in the repository.

Found it, https://github.com/kwart/jd-cmd/blob/master/jd-cli/src/main/bin/jd-cli

[oxr463]

Consider modifying the startup script (jd-cli) to use this instead:

DIR=$( dirname $( readlink -f ${BASH_SOURCE[0]} ))

Because it works with symlinks.

This is not POSIX-compliant, (See: https://stackoverflow.com/a/29835459/8507637).
