[gimp] meson: do not show "profile support: yes" when HEIC support is OFF.

    meson: do not show "profile support: yes" when HEIC support is OFF.
    
    Note that profile support also affect AVIF but since AVIF support came
    anyway after libheif 1.4.0 (which is when color profile support
    appeared), there is no way to differentiate there.
    Thanks to Darix for noting the miss.
