[PATCHv2] ctf-front-end: Add test for alias symbols

["Guillermo E. Martinez" <guillermo.e.martinez@oracle.com>]

This patch v2 to add a new test case in the ctf-front-end test suite to
to test for alias symbols.

Changes from v1:
  + I forget to add the correct tests/data/test-read-ctf/test-alias.o.abi file.

Comments will be appreciated!.

Thanks,
guillermo
