Log:
[pstl] Default to the serial backend when unspecified

This is a stopgap measure to make it easier to integrate the PSTL into
libc++. In the future, we should have a system similar to what libc++
does, where we specify settings at configuration time and generate a
__config_site header that is part of the PSTL.
