asterisk-chan-lantiq: Fix nonshared builds

- Cosmetic: change version from 1.0 to git checkout date.
- Remove dependency on asterisk, as otherwise the package won't be
  built by the build bots.
- Without asterisk in the staging directory the asterisk headers are
  now taken from an archive in $(DL_DIR), which is stored there by the
  asterisk package.
- The naming of the package needs to be changed, as without the
  dependency on asterisk it would otherwise mess with asterisk's
  menuconfig layout.
