Log texvc errors in 'texvc' log channel

This patch adds wfDebugLog() calls for conditions related to texvc invocations.
The logs are grouped under a 'texvc' group, added for this purpose. The reason
for logging into a separate channel is that the Math channel is too verbose for
production use on the Wikimedia cluster.
