Subject: [PATCH] Coverage: shasum command not supported on CentOS

Centos has sha1sum, instead of "shasum -a1". Modified script to
check for existence fo shasum, and if not present, use sha1sum
for coverage test processing. If neither are available, an error
will be reported and processing stopped.
