[Buildroot] [PATCH] infra/pkg-generic: use readlink instead of realpath

[Yann E. MORIN]

realpath is missing on oldish distributions, like Debian 7, which is
still sued in the wild.

Use readlink instead; that has been available since the dawn of ages now
(well, coreutils had it in 2003).

Seems like I forgot to say that I had applied this patch, on December
2. So: applied, thanks!
