buildtools-tarball: Add nativesdk-ncurses-terminfo-base

We've been seeing issues where some TERM values don't work well with the
tarball. These show up as escape codes coming from simple python calls such
as printing the python version. Adding the terminfo goes part way to addressing
the problem, the remainder is ensuring the relocation code correctly searches
the right path for it (which will be in a follow on patch).
