[Buildroot] [PATCH v2, 1/1] package/libvirt: fix libvirtd dependency

[Fabrice Fontaine]

Add a dependency to BR2_TOOLCHAIN_USES_GLIBC to fix the following
libvirtd build failure raised since commit
f81242ae4fb64ab85af5d38e70246222276552ae:

Makefile:575: *** libbsd is in the dependency chain of netcat-openbsd that has added it to its _DEPENDENCIES variable without selecting it or depending on it from Config.in.  Stop.

BR2_TOOLCHAIN_USES_GLIBC is only needed by netcat-openbsd, but a
dependency on BR2_TOOLCHAIN_USES_GLIBC || !BR2_PACKAGE_NETCAT_OPENBSD
can't be added as it will create a circular dependency

An other option would be to revert
f81242ae4fb64ab85af5d38e70246222276552ae and to always mandate C++ even
if it is only needed by nmap-ncat
