Since the bump to 3.0.9 with buildroot commit
3c66f65a6a549930870f2c0d98abb5ca9321d2a5 the configure script of
(host-)libopenssl needs the FindBin perl module on the host:

Can't locate IPC/Cmd.pm in @INC (you may need to install the IPC::Cmd
module) (@INC contains: /home/buildroot/autobuild/instance-1/output-1/
build/host-libopenssl-3.0.9/util/perl /home/buildroot/autobuild/instance

19.

As this is needed for both libopenssl and host-libopenssl (which does not
have a corresponding config symbol in the .config), we have to require it
unconditionally.
