ANDROID: preserve CRC for xhci symbols

In release 5.10.178 a new .h file was included in the xhci code, which
caused the CRCs to change as some structures changed into "real"
structures instead of anonymous definitions.  So preserve the CRCs by
commenting out the #include if GENKSYMS is being calculated.
