plan9port: Install into "$output/plan9" instead of "$output".

This fixes <https://issues.guix.gnu.org/67329>.

* gnu/packages/plan9.scm (plan9port)[arguments]: Add 'strip-directories'.
<phases>: Use "$output/plan9" as PLAN9_TARGET.  Remove 'wrap-executables
phase, instead invoke "./INSTALL -c" to change hard-coded /usr/local/plan9
paths.
