Remove top-level manifest.scm as package in guix.scm is sufficient

* manifest.scm: Removed in favor of guix.scm and the blog-rekahsoft-ca package definition within it

* guix.scm: Add environment variable PS1 that was formally set by manifest.scm

* README.org (Start Development Environment): Update guix commands used now that there is no top-level manifest.scm
