Userspace aliases should include all wrappers by default

[ZymoticB]

Shouldn't need to specify, for example, that read is an alias of read (due to the symbol interposition done by pthread and likely others.). This is just a convenience thing.

The only issue here (which isn't deal with as well) is that the function wrapper calls out to whatever symbol the granary shared library is linked against. If an application is linking against a library which overrides some libc symbols then granary will see those symbols and will alias them but the wrapper will be calling out to the wrong symbol. Not sure how to resolve this part though!

I think this is partially dealt with based on how all aliases/detach points are resolved on a per-library basis on initialization (by scanning /proc/self/maps). This isn't solved for the general case (dlopen) though.
