[tor/master] Lower log level of unlink() errors in networkstatus_set_current_consensus().

commit 04290724957e14710646a5c28bd3230710466c92 Author: Alexander Færøy <ahf(a)torproject.org> Date: Thu Apr 25 01:50:13 2019 +0200 Lower log level of unlink() errors in networkstatus_set_current_consensus(). In this patch we lower the log level of the failures for the three calls to unlink() in networkstatus_set_current_consensus(). These errors might trigger on Windows because the memory mapped consensus file keeps the file in open state even after we have close()'d it. Windows will then error on the unlink() call with a "Permission denied" error. The consequences of ignoring these errors is that we leave an unused file around on the file-system, which is an easier way to fix this problem right now than refactoring networkstatus_set_current_consensus().
