ncurses: Avoid occasional builling failure when having parallel processable task

ncurses failure non-gplv3 build (race issue) like the following \
error information:

| tic: error while loading shared libraries: /srv/home/pokybuild \
/yocto-autobuilder/yocto-slave/nightly-non-gpl3/build/build/tmp/\
work/x86_64-linux/ncurses-native-5.9-r8.1/ncurses-5.9/narrowc/lib\
/libtinfo.so.5: file too short
| ? tic could not build /srv/home/pokybuild/yocto-autobuilder/\
yocto-slave/nightly-non-gpl3/build/build/tmp/work/x86_64-linux/\
ncurses-native-5.9-r8.1/image/srv/home/pokybuild/yocto-autobuilder\
/yocto-slave/nightly-non-gpl3/build/build/tmp/sysroots/x86_64-linux\
/usr/share/terminfo
| make[1]: *** [install.data] Error 1

This is a race issue which is caused by
install.libs and install.data:

1) install.data needs run tic
2) tic needs libtinfo.so
3) install.libs would regenerate libtinfo.so
4) but install.data doesn't depend on install.libs, and they can run
   parallelly

So there would be errors in a very critical condition: tic is begining
to run at the same time when install.libs is generating libtinfo.so, and
this libtinfo.so is not integrity, then there would be the  above error.

Let task install.libs run before install.data for fixing this bug.
