SlackBuild for age

[ccarcaci]

Hello, I've created the SlackBuild package for age to help Slackware users to install the binaries.

You can find the SlackBuild code here https://github.com/ccarcaci/slackbuilds/tree/main/age

I'd like to have your opinion before submitting the package and make it available to the Slackware community.

Thanks :)
