That's inside test-container.c and should be referring to the
test-root's root (i.e. <full path to>/br/build/glibc-867196a7635/testroot.root/lock.fd

Is there a UID mismatch between the two systems?  Did you run a full
"make check" at least once, to build the initial testroot?  It does a
full "make install" into $build/testroot.pristine/ to use as the basis
for the container's root.
