pldmtool: GetPLDMCommands is not spec-compliant

[FHomps]

ver32_t version{0xFF, 0xFF, 0xFF, 0xFF};

pldmtool's GetPLDMCommands command sends a placeholder version field that is not compatible with the DMTF's DSP0240.

Note that this shouldn't be fixed without also fixing issue #27.

pldmtool hardcodes the version as {0xff, 0xff, 0xff, 0xff} for every request , ideally that should be fed as input through the pldmtool commands from the user and that should be filled inside the request message.

And also per base spec :

A value of 0xFF in the "update" field indicates that the entire field is not present. 0xFF is not allowed as a value for the "major" or "minor" fields. Software or utilities that display the version number should not display any characters for this field.

minor and major fields should never has 0xFF, its a spec violation.
