chore (lfortran): remove unnecessary compiler flag set in `CMAKE_Fortran_COMPILE_OBJECT`

Compilation with `--generate-object-code` flag is responsible for the build failure described
in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1091023. This flag is better passed via
the `CMAKE_Fortran_FLAGS` variable to avoid overriding essential compiler behavior.
