Added support for custom DATA path in shell scripts

When the YACY_DATA_PATH environment variable is set, shell scripts will
now use the given path instead of relative ../DATA which remains the
default when the variable is not set.

Necessary in the context of Snap package (see issue #254) as YaCy is
started with startYACY.sh and an absolute DATA parent path in parameter.
