feat(ncurses): drop configure-project-installer, inline autotools build

Switch fromsource:ncurses to its own inline autotools build:

* paths derived from pkginfo.install_file()
* configure + make + install in a single sh -c
* fixed -j8
* sysroot include dir wrapped in _sys_usr_includedir() helper
* shell cp -r replaces os.dirs / os.files glob (silent no-ops in 0.4.9)
* declare upstream url + sha256

Build flag: --without-cxx-binding.
ncurses 6.4's C++ binding doesn't compile against gcc 14+ libstdc++
(NCURSES_BOOL alias for `unsigned char` clashes with std::bool in
<compare>/<exception_ptr>/<type_traits>). The C ncurses libs we
actually ship (libform/libmenu/libncurses/libpanel/libtinfo) are not
affected.

Verified end-to-end in xlings 0.4.9 iso:
  ✓ configure -> make -j8 -> make install
  ✓ produced libform.so.6.4, libmenu.so.6.4, libncurses.so.6.4,
    libpanel.so.6.4, libtinfo.so.6.4 + soname symlinks
  ✓ headers (incl. ncursesw/ subdir) copied into subos sysroot

Cluster B leaf 3/8.
