~/.bin and ~/.local/bin are added to the path by /etc/skel/.profile
which is shipped in the bash package.
It's debatable whether these should be added to the path
unconditionally, or only if they exist. It is convenient to have the
directories automatically available on the path as soon as they are
created, without having to relogin / re-source the shell config;
conversely, it means a couple of extra pointless stats on every exec()
call.
Regardless, though, I don't think it's correct that your certification
suite should throw errors as a result of directories on the PATH not
being present on the filesystem.

Title:
16.04.3 deployments include non-existent directories in $PATH

Bug description:
Noticed this while doing regression testing on 16.04.3, and a number
of customers have asked with concerns as well during their testing.
I don't know exactly when this started, but we just started noticing
it with 16.04.3 (4.10) but $PATH by default now includes several
directories that do not exist:
ubuntu@above-ox:~$ find $(echo "$PATH" | sed -e 's/:/ /g') -maxdepth 1 -type
dfind: ‘/home/ubuntu/bin’: No such file or directory
find: ‘/home/ubuntu/.local/bin’: No such file or directory
/usr/local/sbin
/usr/local/bin
/usr/sbin
/usr/bin
/sbin
/bin
/usr/games
/usr/local/games
find: ‘/snap/bin’: No such file or directory
We noticed this because it was causing a resource job in the
certification suite to suddenly start failing (the failure was not
catastrophic, but it did appear to customers who were concerned.
I've verified this on both s390x and amd64 16.04.3 deployments via
MAAS 2.2.
