libc/csu: Unify INIT_RELOCS across architectures
Some architectures don't need any arguments, whilst others need auxargs,
which they get by passing in env thanks to INIT_RELOCS referencing the
local variable in __libc_start1(_gcrt) by name. This is unnecessarily
confusing, fragile (one has to look at INIT_IRELOCS's definition to see
that it uses env) and duplicates code between architectures.
Instead, implement it more like rtld-elf. Each architecture provides an
ifunc_init that takes the auxargs directly, and those that don't need it
can just ignore it.
