Jörg Thalheim 82caa0683d [Scripts] Make bash shebangs portable
Unlike /usr/bin/env which is a Posix standard, there is no guarentee
that /bin/bash exists. This is the case for operating systems such
as FreeBSD, NixOS and Guix. By using /usr/bin/env we also give
the user the option to provide their own bash in a different path
by setting the $PATH environemnt variable.
Distributions usually provide their own packaging wrappers
to fixup shebangs upon installation, however those are not convienent
to use when developing in the source tree.
