[fedora-astronomy] Build iraf RPM on fedora

[Olе Streicher]

Hi all,

one more proposal regarding directory structure: According to the 
freedeskto.org, the directories imlib$ and cache$ should go into the
user's home dir on default:

http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html

which leads to a change in mkiraf.csh (see below).
This creates and uses the files

${HOME}/.local/share/imdir - as user image directory
${HOME}/.cache/iraf        - as user cache dir

Best regards

Ole
