fips/geo-rep: Replace MD5 with SHA256

MD5 is not fips compliant. Hence replacing
with SHA256.

NOTE:
The hash is used to form the ctl_path for the ssh connection.
The length of ctl_path for ssh connection should not be > 108.
ssh fails with ctl_path too long if it is so. But when rsync
is piped to ssh, it is not taking > 90. rsync is failing with
error number 12. Hence using first 32 bytes of hash. Hash
collision doesn't matter as only one sock file is created
per directory.
