fix(ios): copy iOS NotifeeCore library more carefully during build

there was the possibility on certain OSes (Ubuntu-22 it seems) that
bash would copy into sub-directories with casual usage of paths

now the copy is definitely to an absolute path and won't create erroneous
nested directories regardless of initial state

also it will print what it's copying, for later verification
