libnl: fix RREPLACES and RCONFLICTS for libnl-genl

The libnl-genl.rpm provides libnl-genl-3-200 after the following 2 fixes:
libnl: update to v3.2.28
libnl: fix packaging mistakes

$ rpm -qp --provides tmp/deploy/rpm/core2_64/libnl-genl-3-200-3.2.28-r0.4.core2_64.rpm
elf(buildid) = 4e753b2361ba0b02f162244a87cc0680796e46cc
libnl-genl = 3.2.28
libnl-genl-3.so.200()(64bit)
libnl-genl-3.so.200(libnl_3)(64bit)
libnl-genl2
libnl-genl-3-200 = 1:3.2.28-r0.4

Note, the libnl-genl2 is introduced by REPLACES_${PN}-genl = "libnl-genl2".

So that we don't need set libnl-genl-3-200 in the RREPLACES and
RCONFLICTS, otherwise it would cause do_rootfs errors when install both
libnl-genl.rpm and lib32-libnl-genl.rpm:

Computing transaction...error: Can't install libnl-genl-3-200-1:3.2.28-r0.0@core2_64: conflicted package libnl-genl-3-200-1:3.2.28-r0.0@lib32_x86 is locked

We didn't meet this error before was because there was no libnl-genl.rpm,
but libnl-3-genl.rpm, and it doesn't provide libnl-genl-3-200 by default.

Remove libnl-genl-3-200 from RREPLACES and RCONFLICTS will fix the problem.
