Makefile: Use auto header dependence to fix 6 dependence issues

[vemakereporter]

Hi, I've fixed 6 dependencies missing Those issues can cause incorrect results when fzy is incrementally built. For example, any changes in "src/tty_interface.h" will not cause "src/fzy.o" to be rebuilt, which is incorrect. I've tested it on my computer, the fixed version worked as expected. Looking forward to your confirmation. I fix them by using the Auto-Dependency Generation technique mentioned here: http://make.mad-scientist.net/papers/advanced-auto-dependency-generation/

Thanks Vemake
