net/tap: add CRC stripping capability

CRC stripping is executed in the kernel outside of TAP PMD scope.
There is no prevention that the TAP PMD will report on Rx CRC
stripping capability.
In the corrupted code, TAP PMD did not report on this capability.
The fix enables TAP PMD to report that Rx CRC stripping is supported.
