update_udev_hwdb: clean hwdb.bin

Steps to reproduce:
echo "IMAGE_INSTALL_append = \" udev-hwdb lib32-udev-hwdb\"" >> conf/local.conf

When install both udev-hwdb and lib32-udev-hwdb as above,
there comes below do_populate_sdk error:
 $ bitbake core-image-sato  -c populate_sdk
 ERROR: Task (/path/core-image-sato.bb:do_populate_sdk) failed with exit code '134'
 NOTE: Tasks Summary: Attempted 5554 tasks of which 0 didn't need to be rerun and 1 failed.

 $ cat /path/tmp/work/qemux86_64-poky-linux/core-image-sato/1.0-r5/pseudo/pseudo.log
 [snip]
 inode mismatch: '/path/tmp/work/qemux86_64-poky-linux/core-image-sato/1.0-r5/sdk/image/usr/local/oecore-x86_64/sysroots/core2-64-poky-linux/lib/udev/hwdb.bin' ino 427383040 in db, 427383042 in request.
 [snip]

It is because both udev-hwdb and lib32-udev-hwdb will generate
${SDK_OUTPUT}/${SDKTARGETSYSROOT}/lib/udev/hwdb.bin during do_populate_sdk
and it triggers pseudo error.

So clean hwdb.bin before generate hwdb.bin to avoid conflict to
fix the above do_populate_sdk error.
