perf symbols: Add support for reading from /proc/kcore
In the absence of vmlinux, perf tools uses kallsyms for symbols. If the
user has access, now also map to /proc/kcore.
The dso data_type is now set to either DSO_BINARY_TYPE__KCORE or
DSO_BINARY_TYPE__GUEST_KCORE as approprite.
This patch breaks the "vmlinux symtab matches kallsyms" test. That is
fixed in a following patch.
