rbenv install: fix substituting $HOME with "~" (#2501)

Browse source 
Depending on bash version, the expression `${var/$HOME\//~/}` will not have
effect because the "~" character in the replacement expression is expanded.

The updated approach is a bit of a mouthful, but it avoids using "~" in a
substitution pattern, while also guarding against values of HOME that are
blank or when HOME is literally just "/".
