internal/fakecgo: improve generation of OS-specific symbols (#384)

The fakecgo package autogenerates some symbols that are not used on all supported OSes.
For example, pthread_self is only used on Darwin.

Those symbols shouldn't "leak" into OSes not using them, but they currently do. The Go linker
is smart enough to avoid adding them in the final binary, although this is a bit brittle. Regardless,
it is confusing to have a symbol defined on a platform that doesn't support it, like
purego_pthread_get_stacksize_np which is only supported on Darwin.

Note that I plan to grow the list of OS-specific symbols as part of #343, so this problem is only
going to get worse.
