tests: qemuxml2argv: Remove testing of post startup change to 'cachemode' for shared disks

Testing that the cachemode is properly recorded to the configuration
after startup does not add much value and overcomplicates the xml2argv
test.

Remove the 'disk-shared' test with old capabilities as the test with
real capabilities covers the code sufficiently.
