When doing `DIR NUL` findfirst will actually return success
with an attribute indicating a device exists with that name.
MS-DOS shows 'File not found' in this case, but Comcom
(and also FreeCOM) can display invalid data, so let's
correct that. Since the required constant _A_DEVICE isn't
always present in `dos.h`, let's define it when necessary.
Before:
~~~
C:\>dir nul
Volume in drive c is IR DXXXXS C
Directory of c:\
2025-10-30 16:41 0 NUL
1 file(s) 0 bytes
0 dir(s) 48.7 GB free
~~~
With patch:
~~~
C:\>dir nul
Volume in drive c is IR DXXXXS C
Directory of c:\
File not found

It seems the runner image has a strange package state, so we need to `apt update` before trying to install any packages.
