    fdtoverlay: Switch from using alloca to malloc
    
    alloca entails a complicated header situation when using other platforms, where
    some split it out in alloca.h while others include it as a standard part of
    stdlib.h.
    
    The cons don't seem to outweigh the pros, so switch it to malloc.
