An example poudriere-devel pkgclean failure, multiple issues involved

When I just tried to pkgclean -a I got:

# poudriere pkgclean -jmain-CA7 -a -y
[00:00:00] Gathering all expected packages

So I ended up doing:

# rm /usr/local/poudriere/data/packages/main-CA7-default/.real_1632249158/All/*

This may have been tied to the relative timing of the last bulk build
(where the final port failed to build) and when the /usr/ports the jail
was bound to was later updated before the pkgclean. The packages were
those form attempting a build of emulators/mame (targeting armv7 on
aarch64).

But it is not clear to me that pkgclean -a -y should avoid the complete
delete in the above context.

There are also the "unexpected operator" syntax errors and the
POUDRIERE_BUILD_TYPE error once "Packages stuck" happened.

For reference:

# poudriere version
poudriere-git-3.3.99.20210907_1
