libusb-compat: fix a build issue with undefined PATH_MAX

libsigrok build failed because of PATH_MAX not being defined in usb.h.
On linux it is defined in linux/limits.h, but usb.h only includes
limit.h. Add a patch fixing the header in libusb-compat.

While we're at it: remove the patch numbering from previous patch.

+Subject: [PATCH] fix a build issue on linux
+
+On linux PATH_MAX is defined in linux/limits.h. If we include usb.h
+without previously having indirectly included it, the build fails.
