Fixed SAP component build

- Updated URL for fusesource-third-party-internal repo
- Fixed unit test configuration of camel component to pick
  up required native lib which enable unit tests to run
- Added profile to select component examples for build

The native SAP libraries required by SAP camel component unit tests for 32 and 64 bit versions of Linux, Window and Mac OSX have been deployed to the Fusesource Releases 3rd Party (internal, obsolete) repository.

NOTE: Changed artifact version of component project back to '7.3.0.redhat-SNAPSHOT'; not sure why these were changed. Will change back if this is incorrect.
