travis-ci: added fix for mojave mac build
    
Corrected the minimum version of OSX image on which the target
binaries are to be deployed. CMake uses this value for the
-mmacosx-version-min flag and to help choose the default SDK.
The CMAKE_OSX_DEPLOYMENT_TARGET depends on DARWIN_VERSION:
DARWIN_VERSION <= 10.12 -> CMAKE_OSX_DEPLOYMENT_TARGET = 10.6
DARWIN_VERSION >= 10.13 -> CMAKE_OSX_DEPLOYMENT_TARGET = 10.14

Fixes #3797
