README.md: iRODS4: use MD5 for CKSM to work #10

Hi Roberto,

I ran into an issue where Globus.org would fail at the file verification stage, failing to parse the output of CKSM:

Globus had an unexpected failure. Please contact support@globus.org

fxp: fxp/parse.cpp:28: std::string fxp_parse_md5_checksum_response(conn::Response*): Assertion `isalnum(ret[i])' failed.
Exited due to signal 6 (SIGABRT)

I saw in GridFTP server log that the syntax returned an base64-encoded SHA2 hash:

[24929] Tue Jun  2 14:26:07 2015 :: smtp.globusonline.org:33480: [SERVER]: 226 Transfer Complete.
[24929] Tue Jun  2 14:26:07 2015 :: smtp.globusonline.org:33480: [CLIENT]: CKSM MD5 0 -1 ~/Ducklings_Beware.jpg
[24929] Tue Jun  2 14:26:07 2015 :: iRODS: rcDataObjChksum: collection=/BeSTGRID-I4-DEV/home/vlad/Ducklings_Beware.jpg
[24929] Tue Jun  2 14:26:07 2015 :: smtp.globusonline.org:33480: [SERVER]: 213 sha2:47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU=

while the default MD5 hash would also be just hex-dumped:

[13001] Tue Jun  2 15:43:59 2015 :: smtp.globusonline.org:54748: [CLIENT]: CKSM MD5 0 -1 ~/Ducklings_Beware.jpg
[13001] Tue Jun  2 15:43:59 2015 :: iRODS: rcDataObjChksum: collection=/BeSTGRID-DEV/home/vladimir.mencl/Ducklings_Beware.jpg

I have added instructions to README.md to change the iRODS hash scheme to MD5 - courtesy
