Missing .so symlinks break stuff

[C0rn3j]

When the binaries are downloaded, there's a missing libSDL3.so.0 library.

% ldd libSDL3_image.so
        linux-vdso.so.1 (0x00007f143369d000)
        libSDL3.so.0 => /usr/lib/libSDL3.so.0 (0x00007f1433200000)
        libc.so.6 => /usr/lib/libc.so.6 (0x00007f143300f000)
        libm.so.6 => /usr/lib/libm.so.6 (0x00007f1432ef1000)
        /usr/lib64/ld-linux-x86-64.so.2 (0x00007f143369f000)

The .so files should look more like so:

/usr/lib/libSDL3.so ⇒ libSDL3.so.0
/usr/lib/libSDL3.so.0 ⇒ libSDL3.so.0.4.2
/usr/lib/libSDL3.so.0.4.2

Though the main problem is the missing libSDL3.so.0 which is actually used by the other libraries themselves.

This seems to have partially caused Taiko2k/Tauon#2052.
