hidapi: new package

[Thomas:
 - use BR2_INIT_SYSTEMD instead of BR2_PACKAGE_SYSTEMD for the
   libgudev handling. This is consistent with what we do in libmbim,
   modem-manager and network-manager. Only udisks is diverging from
   this by using BR2_PACKAGE_SYSTEMD.
 - Fix the license info: it is GPLv3 *or* BSD-3c *or* the specific
   HIDAPI license. Added LICENSE-orig.txt to LICENSE_FILES.]
