Use absolute acl-config path in xdmod-ingestor

[jtpalmer]

Description

Changes the acl-config invocation from xdmod-ingestor to use an absolute path.

Motivation and Context

It is possible that other executables name acl-config may exist in the PATH of the user running xdmod-ingestor. (This just happened to me.)

This may result in the wrong acl-config being executed. This change prevents that and ensures that the correct file is executed.

Tests performed

Tested manually.
