util/cbfstool: Replace swab.h with commonlib/bsd/sysincludes.h

Browse Source 
Instead of maintaining another set of byteswapping functions in
cbfstool, this change removes swab.h and replaces it with
bsd/sysincludes.h from commonlib. Callers have been updated to use
be32toh/be64toh/htobe32/htobe64 instead of ntohl/ntohll/htonl/htonll
respectively.
