Change UTF8 chars in Kconfig help text about Oprofile AMD barcelona

Fixes screwing up text output when doing a make oldconfig and viewing
help text of "OProfile AMD IBS support".  When the terminal is
not using an UTF8 locale / LANG.  "make config" breaks terminal output
and its not possible to continue.
