util/osdep: Remove some early cruft

The include for statvfs.h has not been needed since all statvfs calls
were removed in commit 4a1418e ("Unbreak large mem support by
removing kqemu").

The comment mentioning CONFIG_BSD hasn't made sense since an include
for config-host.h was removed in commit aafd758 ("util: Clean up
includes").

Remove this cruft.
