audio/harp: fix build on 13- and 14-

Multiple "plugins" defined a translation-unit global variable `h`,
leading to linker errors. Those are supposed to be used only
from that TU, so make them static, drop BROKEN, and bump
PORTREVISION because there is a microscopic change in symbols
in the package.
