[v2] bitbake.conf: ignore ${HOME}/. files in pseudo

vim and less always write to these files in users home directory.
Using vim and less via pseudo in "bitbake -c devshell recipe" and
outside of pseudo triggers pseudo aborts which makes interactive
use of devshell difficult. Fixes vim and less crashes and related
pseudo log entries:

inode mismatch: '/home/builder/.viminfo' ino 33270730 in db, 33269736 in request.
inode mismatch: '/home/builder/.lesshst' ino 33270625 in db, 33270730 in request.

Ignoring all files with ${HOME}/. in path since many tools
with e.g. GNU readline support will write files there.
Hopefully no-one compiles in such paths.

Please add a comment here because it would be all too easy to mistake 
that for something that can be simplified to just "${HOME}" (by expecting 
normal path rules). E.g.:

# Ignore all files and directories starting with a . in the ${HOME} directory

Yes, I can add a comment.

Unfortunatetly I already run into problems with full ${HOME}/. filter
in trusted-firmware-a from meta-arm. Looks like the dtb etc tooling
does not work correctly and files end up without root owner:

ERROR: trusted-firmware-a-2.12.1+git-r0 do_package_qa: QA Issue: trusted-firmware-a: /optee_ffa_spmc_manifest.dtb is owned by uid 1004, which is the same as the user running bitbake. This may be due to host contamination [host-user-contaminated]

Since pseudo uses strncmp() quoting the dot etc should not have any effect.

I will revert to v1 of this with a comment. That I tested for a few days
without any issues. I used vim and less extensively when rebasing
a number of patches in tf-a, edk2, u-boot, optee etc. As I feared
lots of tools are using ${HOME}/. paths in various ways.
