misc: fix misc. shebangs

* One #!/usr/bin/env python and three #!/usr/bin/python were overlooked
  in all the other python fixups. Ugh.

* Two new python files missed the memo about #!/usr/bin/python3.

* One #!/usr/bin/env bash.
  Various distribution packaging policies have strong wording about
  the use of #!/usr/bin/env ...

  Note: this patch does not change the use of #!/usr/bin/env bash in
  the two files extras/{clang-checker.sh,check_goto.pl} as these are
  not included in any packages. (Although I'm not actually sure why
  anyone would ever use '/usr/bin/env {sh,bash}' as I'm not aware of
  any version-specific differences like there are with, e.g., python.)

* One #!/usr/bin/bash.
  On Fedora and CentOS > 6, /bin is a symlink to /usr/bin, so it
  makes little difference. But Debian & Ubuntu still have separate
  /bin and /usr/bin; and sh and bash are in /bin, not /usr/bin.
  (Historically, in BSD and SYSV Unix it was /bin/sh.)

  Note: Fedora and CentOS package build runs a script that converts
  all /bin/sh and /bin/bash to /usr/bin/sh and /usr/bin/bash.
