CI: Some improvements.

* Only build packages that are actually present in source tree.
  This should fix detection of renamed package folders, including case
  sensitivity changes.

* Fix case sensitivity of Bintray account names.
  Bintray accounts are now properly referenced in lowercase, and compared
  without case sensitivity against the GitHub account for enabling deployment.

* Initialize target list when converting lines to array.
