Fix container tests for SUSE distros

[siddharthab]

Currently, the container tests in our CI are failing for Leap and Tumbleweed with messages like:

ld.lld: error: relocation R_X86_64_PC32 cannot be used against symbol 'stdout'; recompile with -fPIC

I have not given too much thought into why this could be happening. One thing I noticed is that the sles-12.4 LLVM release that we are using also needed libc++ from the system, so I had to now update the zypper packages to include libcc+1.

Anyway, I don't typically work in SUSE, so any help from the community will be appreciated.
