Respect configured BASEDIR for default values
Respect configured BASEDIR for default values

If BASEDIR is set in config.sh, this does not modify the (default) values
of either PRIVATE_KEY, WELLKNOWN or LOCKFILE. One needs to manually specify
those three config variables in config.sh, if a different BASEDIR
should be used by letsencrypt.sh.

This commit makes letsencrypt.sh fully aware of a configured BASEDIR.
