kconfig: use pkg-config for ncurses detection
From Linux commits be8af2d54a66 ("kconfig/lxdialog: get ncurses CFLAGS
with pkg-config") and 7285996aa000 ("kconfig: nconfig: fix multi-byte
UTF handling").
Our Kconfig was built off of Linux's back in 2013, and it's showing its
age with more recent toolchains and libraries.
