While the trace shows nothing wrong - isn't this same issue as you had with 
dmeventd ?

Both services needs to be masked together with their sockets on testing 
machine for testing services (unless you build test package which then is able 
to run with installed binaries)

Although the socket for testing should be different from 'real one'.

but anyway - you need to provide trace from blocking run:

make check_lvmetad T=lvmetad-dump  VERBOSE=1 LVM_TEST_AUX_TRACE=1 &>/tmp/log.txt
