Omar Sandoval ee2dd07f57 libelf: handle PN_XNUM in elf_getphdrnum before shdr 0 is cached ...

__elf_getphdrnum_rdlock() handles PN_XNUM by getting sh_info from
elf->state.elf{32,64}.scns.data[0].shdr.e{32,64}. However, that is only
a cache that may or may not have been populated by elf_begin() or
elf{32,64}_getshdr(); if it hasn't been cached yet, elf_getphdrnum()
returns 65535 (the value of PN_XNUM) instead. We should explicitly get
the shdr if it isn't cached.
