Pablo Sabater a5142f44dc lib-log-graph: move check_graph function
check_graph is a function shared in the test files t4215 and t6016 used
to format the output graph, but instead of being in a file called by
both test, the function code is repeated in each file.

Move check_graph to lib-log-graph.sh file which both tests already
import graph functions from, renaming it to lib_test_check_graph.

This function is needed for the following commit which includes graph
tests in a new file and requires check_graph.
