Switch macOS default bootstrap shell
Newer macOS releases with SIP enabled can cause problems when trying
to use certain environment variables such as LD_LIBRARY_PATH under
system shells, i.e. /bin/*sh. Currently we have various workarounds
for this across the tree.
I propose changing bootstrap to default to pdksh for these releases,
as using a shell outside of system paths still works.
I've tested this in a bulk build using --full, the results of which
and can be compared to the previous regular build using /bin/bash here
(though note that my bulk build hosts disable SIP so do not see the
problems that others do):
I don't see any causes for concern, so would like to commit the

We're quite close to freezing, but I think this should be safe, and
will resolve some issues that people are seeing.
