[FEATURE_REQUEST] support openssl checksum format too

[Guenter Knauf]

Hi all,
suprisingly I just found that md5sum and sha1sum also accept the formats
of the md5 and sha1 tools as input with option -c. There's though a
third checksum format which is produced by the openssl tool which only
slightly differs to the format from md5 and sha1 - two blanks are
missing ...
output of 'md5 file':
MD5 (httpd-2.2.14.tar.bz2) = a5226203aaf97e5b941c41a71c112704
output of 'openssl md5 file':
MD5(httpd-2.2.14.tar.bz2)= a5226203aaf97e5b941c41a71c112704
output of 'sha1 file':
SHA1 (httpd-2.2.14.tar.bz2) = eacd04c87b489231ae708c84a77dc8e9ee176fd2
output of 'openssl md5 file':
SHA1(httpd-2.2.14.tar.bz2)= eacd04c87b489231ae708c84a77dc8e9ee176fd2

I think that it cant be hard to make md5sum and sha1sum accept the
openssl format too.

thanks, Günter.
