[LEDE-DEV] [PATCH] openssl: remove cause of buildbot failures

[Val Kulkov]

Compiling openssl generates a number of error messages as make executes
openssl on host, producing errors: "wrong ELF class: ELFCLASS32". These
errors trigger buildbot failures as described in issue 5432 [1] at
openwrt/packages Github repo.

This patch fixes issue 5432 by removing demo certificates from the
build directory. The demo certificates are not necessary for compiling
or packaging openssl on OpenWrt.
