apt: fix nativesdk-apt build failure during the second time build

Run following commands:
bitbake nativesdk-apt
bitbake nativesdk-apt -c install -f

The second command's do_install will fail with following error:

During the first command, do_install task changed tagfile-keys.cc, this
will make tagfile-keys.cc is newer than the built tagfile-keys.cc.o. So the second
do_install will rebuild tagfile-keys.cc.o. But the header path is
replaced wrongly, so fix the header path
