Ensure calibration library in ur_calibration is always built as static (backport #1667) (#1669)

CMake permits to set the BUILD_SHARED_LIBS=ON variable to specify if add_library calls without specifying explicitly STATIC or SHARED build a shared library.

However, in the case of the calibration library, the library itself is not meant to be installed, so even if BUILD_SHARED_LIBS=ON, the calibration library should be built as STATIC, otherwise at runtime the calibration_correction can fail because it doesn't find the shared library.
