[Buildroot] [PATCH next] libusbgx: fix build with glibc-2.28

[Gwenhael Goavec-Merou]

From: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com>

Without sys/sysmacros.h and with glibc-2.28 build fails with error like:
libusbgx-libusbgx-v0.2.0/src/.libs/libusbgx.so: undefined reference to `minor'
libusbgx-libusbgx-v0.2.0/src/.libs/libusbgx.so: undefined reference to `major'
libusbgx-libusbgx-v0.2.0/src/.libs/libusbgx.so: undefined reference to `makedev'

backport and adapt pr #28 (https://github.com/libusbgx/libusbgx/pull/28)

fix:

The order of the SoB should be the opposite: first the original author,
then you.

Also, please use a Git-formatted patch.

Could you submit a new version with those minor nits fixed?

Also, could you submit a new pull request upstream, because it seems
that Sid Spry is not going to resubmit a proper patch that takes into
account the comments made by upstream.

Thanks!

Thomas
