Enrico Weigelt, metux IT consult 628e94b164 os: let vpnprintf() accept %X ...

Several pieces of the code, as well as drivers are using %X, which
we don't support, so leading to error messages like this:

[2025-02-27 14:28:44] BUG: 'if (f[f_idx])'
[2025-02-27 14:28:44] BUG: ../xserver/os/log.c:538 in vpnprintf()
[2025-02-27 14:28:44] Unsupported printf directive 'X'
[2025-02-27 14:28:44]
[2025-02-27 14:28:44] Backtrace:

In the longer run, we'll have to decide whether we actually want to
implement the upper-case directive or change all callers to lower-case.

But for now it's better to just accept %X and interpret it as lower-case,
in order to fix those error messages. Whether it's printed as upper or
lower case is more or less an aesthetic matter.
