[Buildroot] [git commit] lrzsz: fix repeated target install

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=54bcf87b452c7a7738009fb808d19610fdb31df8
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Closes #4165

Use ln -sf in case destination already exists from an earlier install,
and use install -D rather than cp while we're at it.

Based on patch by Hector Oron <hector.oron at gmail.com>
