pg app: launch script functionality: use sh, rather than bash, as latter may ultimately be removed from macOS

[kencu (Ken)]

The app PortGroup currently generates a launch script like this:

#!/bin/bash
export PATH="/opt/local/bin:/opt/local/sbin:$PATH"
exec /opt/local/bin/gedit

but now that Catalina doesn't use bash we may have to change that to

#!/bin/sh
export PATH="/opt/local/bin:/opt/local/sbin:$PATH"
exec /opt/local/bin/gedit

or perhaps there is a better method.

[ryandesign (Ryan Carsten Schmidt)]

/bin/bash still exists on Catalina so there is no urgent need to change anything. Perhaps it will disappear in a future version of macOS.

Presumably the script is simple enough and POSIX-compliant enough that we should be specifying /bin/sh instead. But if the portgroup's script generation is changed, all ports that use that script generation should have their revisions increased.
