package/openobex: depends on libusb-compat

Openobex looks for libusb.pc provided by libusb-compat, not libusb-1.0.pc
provided by libusb:
https://github.com/zuckschwerdt/openobex/blob/master/acinclude.m4#L171

Openobex links against both libusb (libusb-1.0.so.0) and libusb-compat
(libusb-0.1.so.4):
$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/bin/ircp | grep NEEDED
 0x0000000000000001 (NEEDED)             Shared library: [libopenobex.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libusb-0.1.so.4]
 0x0000000000000001 (NEEDED)             Shared library: [libusb-1.0.so.0]
[...]

This patch changes the dependency in openobex.mk and also selects
libusb-compat.
