  menuconfig: Fix a PREFIX handling bug

This patch fixes a bug where menuconfig corrupts the Makefile.conf
PREFIX variable value by incorrectly trimming the last char in an
attempt to ensure that the value has a trailing '/' char. This would
happen each time the user launches menuconfig and chooses
"Exit & Save All Changes".

Reported by @Jeffrey2019 on GitHub.
Fixes #1248.
