#!/bin/sh and #!/bin/bash in kea sources
looks like we can't decide which shell Kea should use it's script.
Most of them uses
!#/bin/sh but some like e.g. tools/sysrepo_config_defines.sh.sample tools/cql_config_defines.sh.sample went with
My proposal is change all scripts to use
#!/bin/sh and keep it that way in the future.
