9ps: chdir to script basename before including it In the *-suite.9ps files we have stuff like `include "lib.9ps"`, but when ninepscript is called from the *root* directory that include will fail. This is a workaround to allow including file relatively and allows to run the regress suite.

ninepscript: drop per-test `dir' specify the dir only once via ninepscript' -r (mandatory) argument.
