sys-power/powertop: Support ncurses with tinfo

- Patches the configure.ac to fix bug getting libs from pkg-config
- Previous code matched only when both ncursesw and ncurses existed
- Used wrong variable when concatenating to LIBS
- Concatenating to LIBS was redundant anyway since it is done in
  makefile.am
- Upstream patch sent to powertop mailing list [1]

+Subject: [PATCH] Fix configure to support ncurses w/ tinfo
+
+- The existing code checked for both ncursesw and ncurses and if
+  both were not found, NCURSES_LIBS was not set correctly.
+- Removed redundant concatenation to $LIBS since the makefile.am
+  already maps NCURSES_LIBS into LIBS.
+- Patch sent upstream to powertop mailing list [1]
