ncurses 6.1 - patch 20191116

+ modify ncurses/Makefile.in to fix a case where Debian/testing changes
  to the ld --as-needed configuration broke ncurses-examples test
  packages.
+ drop library-dependency on psapi for MinGW port, since win_driver.c
  defines PSAPI_VERSION to 2, making it use GetProcessImageFileName
  from kernel32.dll (prompted by patch by Simon Sobish, cf: 20140503).
