nvi: revise patches to not reference ..

[ryandesign@…]

jeremyhu has alerted me to the fact that some versions of /usr/bin/patch on Mac OS X have a "security enhancement" that makes them refuse to patch files higher up than the current directory. On such systems, trying to install nvi results in the following:

--->  Applying patches to nvi
--->  Applying /Users/rschmidt/macports/dports/editors/nvi/files/patch-common__db.h

The attached patch fixes this.
