app/testpmd: check if CRC strip offload supported

Testpmd set CRC_STRIP offload blindly, this is wrong according offload
API definition, and will cause error for the PMDs that doesn't support
CRC_STRIP like virtual PMDs.

Check if underlying device report this capability and don't set it if
not supported.

Fixes: 0074d02fca21 ("app/testpmd: convert to new Rx offloads API")
