For consistency have the CI use the same build path as
the end-user builds.
Use where.exe from wine-10.0.
CI's version is a stub. Use one that actually works, until the CI gets
updated.
Also, fix broken RtlGenRandom by importing ADVAPI32's GetUserNameW(),
and calling GetModuleHandleW() / GetProcAddress() for SystemFunction032().
Instead of trying to use a fake import lib.
Bonus: Can now use the host system's username as the default for the
steam user name instead of "Noob".
("Noob" is still used as the fallback if this call fails, or the host
system's username is invalid.)
Fix list:
- Make cmd not choke on recursive calls to build_env_x*.bat.
- Create build directories and move build output there instead of
polluting the root of the source tree.
- Make proper debug builds with pdb output.
- Make proper x64 builds of lobby_connect, and steamclient_loader. (lobby_connect_x64.exe, and steamclient_loader_x64.exe)
- Rename x86 build of lobby_connect.exe to lobby_connect_x86.exe.
- Rename x86 build of steamclient_loader.exe to steamclient_loader_x86.exe.
- Make proper distrib directories. (I.e. <release,debug>/<build type>/<arch>/<binaries>.)
