gollvm: tweak cmake rules for aeshash.c to include correct flags

The libgo runtime source aeshash.c contains AES/SSE3-specific
intrinsics that require CPU features not ordinarily used for default
x86_64 compilation. This source file contains a "#pragma GCC target"
directive that asks for the features, but that pragma is not supported
by clang. Prior versions of clang would go ahead and inline in the AES
intrinsics anyhow, but newer versions issue an error. To work around
this, change the compile flags for aeshash.c to include "-maes -mssse3".
