mesa: replace pthread patch with b tread simpler and better every sin…

…gle bionic packet has this patch

use BIONIC instead of ANDROID i still have no idea what the point is with this remake i wish all my drivers had a GNU libc version i can't even load them from glibc is it possible have you been able to load the Vulkan driver from glibc all drivers are bionic

try to focus on the important adding virpipe to this packet

only glibc has virpipe GALLIUM_DRIVER=virpipe has no effect here sigh
