[PATCH modular 5/8] build.sh: allow user to specify an alternate localstatedir

[Gaetan Nadon]

Modules can be configured with --localstatedir to provide an alternate
location for modifiable single-machine data.

The log dir was created relative to the hard-coded "var" subdir.

A LOCALSTATEDIR variable is added which uses the "var" default value.

If a value other than the default value is used,
the CONFCMD emitted will reflect that with --localstatedir option.
