makepkg: trim trailing space from whitespace sensitive vars

This applies to pkgver, pkgrel, and epoch and ensures that any trailing
whitespace outside of the context of the variable declaration itself is
properly trimmed. The Bash parser will ignore this, and so should we.

We don't need to worry about leading space because it would force a
syntax error, or fail validation.
