Since commit fb777be7d2, linking programs
in /tmp will no longer work, since with this commit (hardcoded) /tmp
will no longer be treated a valid temporary directory by the purity
checking logic.
Essentially what that logic does is checking whether the link target is
either relative, in some temporary directory or in the Nix store and if
that's not the case, an error is thrown like in this case:
gcc -c /tmp/build.24.tmp.c -o /tmp/build.24.tmp.c.o
gcc /tmp/build.24.tmp.c.o -o /tmp/build.24.tmp.out
impure path `/tmp/build.24.tmp.out' used in link
collect2: error: ld returned 1 exit status
Note here, that $TMP and $TMPDIR point to /build while the output here
still refers to /tmp. This is because the custom build system of uqm
simply hardcodes /tmp and doesn't honor any of these variables.
To fix this, all we need to do is the latter and we're now using $TMPDIR
instead of /tmp for these compile-tests during configure.
While the pull request[1] introducing said commit has a few comments
regarding other issues and it could still be either reverted or changed,
using $TMPDIR in the uqm build script is entirely backwards-compatible
and shouldn't hurt in any case.

Was disabled when the package was marked as broken in
c333861954. It has since been un-broken,
but the hydraPlatforms exception was left presumably by mistake.
There was no 3.1 for some reason. The old sed-based path patching was
broken and resulted in syntax errors since it was a bit over-eager.
Instead of fixing it, I decided to replace it with a patch file which is
easier to inspect and will fail in a more obvious way next time.
The patch is now applied unconditionally, since it actually applies to
all linux platforms. The changes are localized to linux-specific code,
so it does not hurt to apply it on non-linux platforms as well.
Hedgewars needs a small fix to work with the new version. Done in the
same commit to avoid a broken commit.
- Use Nix store path for the shebang to make this work on systems
without /bin/sh.
- Replace phases by dont*.
- Install jar file to $out/share/papermc rather than $out.
- License gpl3 -> gpl3Only (couldn't find any evidence that this is
gpl3Plus).
