This avoids a situation where the score of lang becomes lower or equal to others
and then figures out the best font according to other properties and the order
of family names.
This typically happens only when our orthography files are the subset of lang
in patterns. i.e. fc-match :lang=en-us to match on en.orth.
In this case, the score is lower than the exact match (en to en) and the partial
match (en to en-us). thus, the result of 'fc-match :lang=en-us' isn't necessarily
same to 'fc-match :lang=en'.
So 35-lang-normalize.conf contains languages only which is available as orth
without countries and tries to update properties to match on orth exactly like:
<match>
<test name="lang" compare="contains">
<string>en</string>
</test>
<edit name="lang" mode="assign" binding="same">
<string>en</string>
</edit>
</match>

In some cases, non-English languages might appears first in current order.
and when having English name with non-English language ID like Google Noto CJK TC,
English name with English language ID will be dropped due to duplicate.
This fixes that issue.
Most of functionality should be moved to FcFreeTypeQueryAll()
for varfonts now though, if doing the same to FcFreeTypeQuery()
returns Null pattern because of inappropriate masking.
This might be not that big deal for varfonts support. but

Currently it fails if the executable extension is .exe, but wine isn't
available (e.g. on Cygwin)
Possibly the check to use this wrapper should be even more restrictive
e.g. checking if cross-building and/or if wine is available.
'salt' attribute affects a cache filename to generate different name from directory name.
This is useful when sharing caches with host on sandbox and/or give a filename differently:
<dir salt="randomdata">/usr/share/fonts</dir>
<remap-dir as-path="/usr/share/fonts" salt="salt for /usr/share/fonts on host">/run/host/fonts</remap-dir>
Applications can read caches as-is for fonts on /run/host/fonts where is mounted from host.
and write a cache for their own fonts on /usr/share/fonts with different name.
