gluon-mesh-vpn-core: fix potential null pointer dereferences

gluon-mesh-vpn-tunneldigger: fix Lua mesh-vpn provider module location

read_stdout can return NULL and thus the return value need to be checked
prior to accessing it.

Signed-off-by: David Bauer <mail@david-bauer.net>

In case the limit_ingress or limit_egress options are not present in
gluon's mesh_vpn section the respondd provider compares a string literal
with a NULL pointer, crashing respondd.

Check both pointers prior to comparing them in order to mitigate this
issue.

treewide: use lua-jsonc instead of lua-cjson for JSON handling during build

64148a9baf14 lua-jsonc: add host build support
c2623391bf42 lua-jsonc: do not link against liblua

I mixed up two separate improvements into one, this change aims to
clarify them based on a suggestion and conversation with @T-X.
