Set the 1.4.0-rc version suffix and adjust SO version

For libclamav's SO version:
- We added two macros to clamav.h so we should increase Current and Age:
  - CL_SCAN_PARSE_IMAGE and
  - CL_SCAN_PARSE_IMAGE_FUZZY_HASH

For libfreshclam's SO version, we only made changes internal to the
library so we only need increase the Revision.
