meson: improve error message for unsupported systems

This adds the current and supported system information to the error message
when an unsupported programmer is requested, making it easier to tell what
the incompatibility is.

TEST=(in mingw-ucrt64) meson setup -Dprogrammer=ni845x_spi build,
     error message says the programmer needs `['windows']/['x86']` but the
     system is `windows/x86_64`.
