prog: speed up resource ctors detection
When we build a list of resource constructors we over and over iterate through
all types in a syscall to find resource types. Speed it up by iterating only
once to build a list of constructors for each resource and then reuse it.
This significantly speeds up syz-exeprog startup time on Raspberry Pi Zero.
