MDBF-794 - Link bintar binaries statically with libncurses

Clients in our binary taballs are linked dynamically with libncurses, which causes a trouble on systems where it is no longer available
As per MDBF-794 only centos7 and debian 10 bintar builders need to link statically with libncurses.

- for debian 10: libncurses.a is already present in /scripts/local/lib/ and -DCURSES_NEED_NCURSES=1 flag is enough to link it statically.
- for centos7: I've rebuilt the image and pushed manually a dev_ tag. libncurses.a was present on the system but not in the library path: /scripts/local/lib/

Tests available at:
- debian10: https://buildbot.dev.mariadb.org/#/builders/187/builds/23
- centos7: https://buildbot.dev.mariadb.org/#/builders/172/builds/292

Reference CMAKE output line:
-- Found Curses: /scripts/local/lib/libncurses.a
