Support docs-libc-html for LLVM_ENABLE_RUNTIMES=libc

[MaskRay]

Summary

D126156 added a docs-libc-html target for LLVM_ENABLE_PROJECTS=libc, but our
bots use LLVM_ENABLE_RUNTIMES=libc.
This patch follows https://github.com/llvm/llvm-zorg/commit/a5243cfccbb955bc00a0934ead25d8f88e40296a for libcxx/libunwind
to support the LLVM_ENABLE_RUNTIMES=libc configuration.

LGTM

Add libc to getLLVMRuntimesDocsBuildFactory as well..

Unfortunately, I don't know how to test this script...

@gkistanova -- does something need to be done for the server to pick up this change? I'm getting a "sphinx publish failed" email every six minutes, so I'd really love to see this fixed. :-D
