[UT2004 Linux Installer] Roundup of Issues (Android 16, Termux)

[DDRRE]

(This is all happening on an unsupported target, but nevertheless):

1. The regex on line 958 isn't accepted by some bash shells (namely, the one running on Termux latest). Error says trailing backslash (\) and likely refers to the \s used in the expression. Running sed -i 's/\\s/[[:space:]]/g' install-ut2004.sh fixes the issue (replacing \s with [[:space:]]).
2. The precompiled unshield throws unshield: cannot execute: required file not found. Installing the dependency natively (pkg install unshield) and removing .local/share/OldUnreal/UT2004/Installer/unshield fixes the issue.

We are deliberately avoiding to create a dependency on sed. I'll need to check which bash version termux ships with, because it should work even on older-ish (not ancient) bash versions.

As for unshield, I'll test; the builds we provide are statically linked, so I'm surprised it complained about a missing library (unless that library is glibc... If termux ships with musl, it's possible that doesn't work, I have not tested that).

But yes, Android support (both the native shell and termux) is very much here be dragons.

As far as I'm aware, termux doesn't have a display server anyway, so I don't think it's a valid target for us.

Termux has X11 support with an additional package. It doesn't yet work with UT2004 (the binary did try to open a window but crashed when not finding AntiDrv for some reason) but we might get there someday.
As for sed I only suggested that as a command to replace the strings inside the script itself when it is published, not on runtime.
And I think the missing library was indeed GLIBC. Getting the package from Termux directly worked fine.
