bitbake: data: drop unused __expand_var_regexp__ and __expand_python_regexp__

First, commit 81efd77987f6decf256967fa16521a40c14d3518 created a copy
of __expand_var_regexp__ and __expand_python_regexp__ when creating
the initial version of data_smart.py. A while later commit
db1c998b31da06d7f3eb09fc6f59a1915b7b549e dropped all references to
these variables from data.py.

This leaves us today with two versions of these variables in the
global scope. However, only those defined in data_smart.py are being
used, in data_smart.py.

Unfortunately there was no indication in the commit log for commit
db1c998b31da indicating why the variables were left in place despite
the functions referencing them were being removed. Additionally
data.py imports data_smart, thus the versions of __expand_var_regexp__
and __expand_python_regexp__ defined in data_smart.py would be used by
all bitbake code, beyond, potentially, some code in data.py which we
know has no references to these variables.

To remove any potential confusion around these variables drop the old
definitions from data.py.
