Since there is no way to modify either steam.sh or the steam binary as they are
hash checked, I took the approach of bypassing steam.sh and create a script
that does its job.
For now it segfaults, but when I try to run under strace, it works perfectly.
Need to check this.
The binaries that get copied to $HOME need patchelf to run, and after that I
need all the runtime libs in the library path. Still not working as I need
glibc2.15.
The script installed with this expression only copies a boostrapper and another
script to the user's home folder. Those also need to be patched to get on with
the installation.
