[libvirt] [PATCH] build: restore support for libyajl 2.0.1
Commit 105756660f944e7db02de3b55b98bb7c11cd03bf was too eager and did
not consider SLE 12 which still has 2.0.1 that does not ship
a pkg-config file.
Similar to how we check for readline, prefer pkg-config if available
and fall back to the old detection code if not found.
NB: this is not a clean revert because we're not reintroducing support
for YAJL 1.
