Provide a tailored error message on Linux 

I just ran into a case where I installed OpenSSL in a docker container but I
forgot to install pkg-config. Right now openssl-sys relies on pkg-config, so
print out a nice error about this.

It looks like you're compiling on Linux and also targeting Linux. Currently this

requires the `pkg-config` utility to find OpenSSL but unfortunately `pkg-config`

could not be found. If you have OpenSSL installed you can likely fix this by

installing `pkg-config`.
