sys-process/unixtop-3.8_beta1-r3: fix compilation on Linux #726052

Albeit not really keyworded, fix compilation on Linux, and add some
other fixes too:
- block sys-process/procps for conflicting /usr/bin/top
- add resize crash patch
- add patch to allow compilation on Linux
- fix curses patch to work with ncurses[tinfo]

Closes: https://bugs.gentoo.org/726052
Package-Manager: Portage-2.3.99, Repoman-2.3.22
