[PATCH libdrm] tests: Use -pthread in CFLAGS instead of -lpthread

[Tomasz Figa]

-lpthread is not always a valid flag to pull pthread support, especially
on Android it will fail to link due to a missing libpthread.so. The more
generic way to build-in pthread support is to use the -pthread CFLAG, so
let's use it instead.
