pinentry: add patch to fix ncursesw include path

Upstream pinentry seems to assume a fixed include path for ncursesw,
while still using pkg-config to check what that path should be.
This results in detecting the library during config failing to include
it correctly during build.

Fixes:

+Subject: [PATCH 1/1] remove hard-wired ncursesw include path
+
+Don't assume that the ncursesw headers are in ../usr/include/ncursesw/..,
+and pkg-config finds the correct include path anyways.
