Fix mkpath abuse in dwim_ref and dwim_log of sha1_name.c
Otherwise the function sometimes fail to resolve obviously correct
refnames, because the string data pointed to by "str" argument were
reused.
The change in dwim_log does not fix anything, just optimizes away
strcpy code as the path can be created directly in the available
buffer.
