InDetTrackPerfMon: Adding build tests

Adding build tests for the functionality of the IDTPM package (RDO->AOD->runIDTPM):

• test_IDTPM_RDOtoOfflTrkAna_v1_build.sh : runs an example of the offline analysis on a few input events
• test_trigAna_IDTPM_RDOtoOfflTrkAna_v1.1_build.py : runs the same test (only temporarily) but using the TrigValSteering configuration, which will be used to define the tests for the trigger analysis.

Other relevant test for the package functionality with a more suitable naming of the tests will be addressed in later MRs.
