md5/sha1sum: Honor the -b flag in the output

The output of md5sum/sha1sum contains a character to indicate
what mode was used to read the file - '*' for binary, and ' '
for text or where binary is insignificant.

This flag character makes a difference for the ffmpeg testsuite.
This testsuite contains a number of reference files (e.g. [1]),
containing the expected md5sum output for those files, which is
checked verbatim.

By making busybox's md5sum honor this flag in the output,
ffmpeg's testsuite can run successfully on top of busybox.

The flag is only partially implemented; in coreutils md5sum,
a later "-t" option overrides an earlier "-b" option. Here,
just check if a "-b" option was specified or not. Neither
flag affects how the files actually are read.
