kdump: fix kdump mapping
When kdump tries to map the program header, it fails to take account
of ehdr->e_phoff being an offset from the start of the ELF "file",
which causes:
Cannot mmap /dev/mem offset: 64 size: 392: Invalid argument
Ensure that we take account of the start address when mapping this.
This fix has been extracted from a larger patch by Vitaly Andrianov
adding support for Keystone 2.
