[PATCH v2 resend 1/3] makedumpfile: make get_elf64_phdr()/get_elf32_phdr() public

[Wang, Xiao/Wang Xiao]

Move the following two functions from internal function to external
function.

get_elf64_phdr(int fd, char *filename, int index, Elf64_Phdr *phdr)
get_elf32_phdr(int fd, char *filename, int index, Elf32_Phdr *phdr)
