esp32/esp32_common.cmake: Allow overriding linker.lf.

Browse source 
Particularly for out of tree builds, one may need to provide alternative or
extra linker fragment files, or specify an absolute path to the default
`linker.lf` file.

In the default case, do nothing, provide a plain `linker.lf`, as before.
