perf kcore_copy: Keep phdr data in a list

Currently, kcore_copy makes 2 program headers, one for the kernel text
(namely kernel_map) and one for the modules (namely modules_map). Now
more program headers are needed, but treating each program header as a
special case results in much more code.

Instead, in preparation to add more program headers, change to keep
program header data (phdr_data) in a list.
