keg_relocate: relocate the interpreter for elf files with INTERP header (Linux)

Browse Source 
Some elf files (e.g. created by rust compiler) have INTERP header despite
their magic header denotes shared object instead of executable.

We should relocate the interpreter elf files as long as they have INTERP header.

This should fix the broken bottles for rust based formulae.
