[ldapvi] Patch for FreeBSD build

[Ulrich Spoerlein]

Hi, attached you'll find a patch to the install target required on
FreeBSD systems.

INSTALL_PROGRAM is usually defined as 'install -s', which will strip
binaries. This of course fails on manpages or documentation. Therefore
use the appropriate INSTALL_DATA to install these files (this also takes
care of permissions).

I hope this patch can make it into the official tree, as that would ease
the porting effort. Thanks!

Cheers,
Ulrich Spoerlein
