CodeFlag.txt and Template.txt should not be installed in lib directory

[DusanJovic-NOAA]

This is the content of the install tree:

install/
├── bin
│   ├── g2c_compare
│   ├── g2c_degrib2
│   └── g2c_index
├── include
│   └── grib2.h
└── lib64
    ├── cmake
    │   └── g2c
    │       ├── g2c-config.cmake
    │       ├── g2c-config-version.cmake
    │       ├── g2c-targets.cmake
    │       └── g2c-targets-release.cmake
    ├── CodeFlag.txt
    ├── libg2c.a
    ├── libg2c.so -> libg2c.so.0
    ├── libg2c.so.0
    └── Template.txt

I think files CodeFlag.txt and Template.txt should not be installed in lib directory, but in <prefix>/share/g2c for example, which is where shareable text files should be located.
