thunderbird Debian release 1:91.5.0-2

This test can't be excecuted e.g. on arm64 due the nature of the used
machine.
Running this check on Intel based architectures should be enough to see
if the config path is reachable.

Adding a new check which is using strace to detect if the thunderbird
application will try to search for the path

 /usr/lib/thunderbird/defaults/syspref

that we have added by a Debian specific patch. That folder isn't a real
folder later, it's a symlink to

 /etc/thunderbird/pref

were we ship the Debian specific default settings for Thunderbird.

If the check is detecting the path isn't accessed by Thunderbird we need
to adjust the patch

 debian-hacks/Add-another-preferences-directory-for-applications-p.patch

Using 'which' for getting the full patch of an binary is deprecated.

Closes: #1002570

Modified patch:
debian-hacks/Add-another-preferences-directory-for-applications-p.patch

Resync patch content with version in the firefox package to prevent
later ignoring of LoadDirIntoArray while package build as this
modification within the patch was wrongly moved previously into an
'#ifdef/#endif' section which isn't active within the build.

Closes: #997841, #1003280

As usual the source code structure has changed between the ESR versions
and this requires some adjustments for the overrides.

Small updates to the overrides rules for the thunderbird package as some
Lintian tags got renamed.

Update to upstream version '91.3.0'
with Debian dir 8df53703065b2f3c4416409c70ebeee6b07e46dd

This reverts commit f935b529.
The newly added patch isn't working well and breaks soem other
architecture like arm64, ppc64el and s390x.

Thunderbird 91.x requires icu devlopment files around => 69.1 while
currently only 67.1 is available in unstable.
As we will never get a version 69.1 available in stable and oldstable
it's save now to use the preshipped icu files instead and disable a
configuratiion that searches for system wide installed packages.
