MGMT-15235: Compile with CGO_ENABLED=1 for amd64 (#699)

https://issues.redhat.com/browse/MGMT-15235
To be FIPS-compliant, CGO_ENABLED=1 flag must be
specified for go code.
This flag along with the base image used doesn't
work for architectures other than amd64.
See previous revert PR for more information
