[Buildroot] [PATCH v4 1/1] pkg-infra/show-info: dump install_{staging, target, images} info

[Vadim Kochan]

provide info if the package will be installed to staging/target/images
destinations. Might be useful for analyzing the packages which
installed for target/staging/images.

v4:
    1) use "install_{target,staging,images}" property name format (suggested by Arnout Vandecappelle)

    2) add and use macro for YES/NO -> true/false conversion (suggested by Arnout Vandecappelle)

    3) add "install_images" property (suggested by Yann E. Morin)

v3:
    1) fix evaluation of true/false value via 'subst' (suggested by Yann E. Morin)

v2:
    1) use oneliner 'if' to dump install_{staging,target} properties
