libelf: Make sure shdrs are valid before storing extended phnum in newphdr.

Creating phdr with more than PN_XNUM phnum requires a valid section zero
shdr to store the extended value. Make sure the shdrs are valid. Also fix
the error when count was too big to store by setting ELF_E_INVALID_INDEX
before failing.
