scripts: enhance the get maintainer error message

When the DPDK_GETMAINTAINER_PATH variable was not set, the error
message from get-maintainer.sh was quite cheap:

$ devtools/get-maintainer.sh --help
usage: get-maintainer.sh <patch>
Cannot execute DPDK_GETMAINTAINER_PATH

Add a more detailed explanation about this variable in the help.
