native.bbclass: deltask package_qa

The native recipe doesn't need package_qa, and it has a race issue with
do_unpack which requires the clean dir of ${S}, then causes error:

NOTE: recipe opkg-utils-native-0.1.8+gitAUTOINC+eae0d8fa44-r0: task do_package_qa: Failed
ERROR: Task 283 (virtual:native:/path/to/opkg-utils_git.bb, do_package_qa) failed with exit code '1'

perl: add explicit configs for Time-HiRes

The compilation of Time-HiRes tries to compile and run the testing
program but definitely fails since we are cross compiling:
Looking for clock_gettime()... ./tmp26733: ./tmp26733: cannot execute binary file
Looking for clock_getres()... ./tmp26733: ./tmp26733: cannot execute binary file

so add explicit configs to avoid the auto detecting.
