steam: bypass valve's bootstrapper.

Browse Source 
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.
