Allow symlinked scripts in autostart

SUMMARY

Allow scripts in devilbox/autostart to be symlinks to scripts elsewhere

Goal

To be able to version control autostart scripts, it is necessary to put a symlink to the script in the autostart directory, instead of the file proper. The file proper can then exist elsewhere and be version controlled.

[HansCz]

Note that the path the symlink points to is inside a mounted volume, so I assume the path is accessible at the time the autostart scripts run.

@HansCz good catch, I wasn't even aware that this did not work. Fix is on the way: devilbox/docker-php-fpm#117

Excellent! :)
