Add support for tarball contents signature

Currently only supported to allow optional image files in BMC tarball.
In order to ensure that the contents of the tarball are the expected
ones as a full package, an additional signature file has been created
for all the signature files in the tarball,
(ex: image-full.sig = hash(file1.sig + file2.sig + file3.sig...)).
Need to check the existence of the file and the signature verification
passed.

Also, added unit test case for the mergeFiles method.

Tested:
Enable `WANT_SIGNATURE_FULL_VERIFY` and ran the following command:

curl -k -H "X-Auth-Token: $token" -H "Content-Type: application/octet-stream"
-X POST -T obmc-phosphor-image-fp5280g2.static.mtd.tar

  "@odata.type": "#Task.v1_4_3.Task",
  "Id": "1",
  "TaskState": "Running",
  "TaskStatus": "OK"
}

And Log output:
`Successfully completed Signature vaildation.`
