Define PN_XNUM if not defined in elf.h

Browse Source 
VxWorks elf.h (nor any other header in its SDK) doesn't contain
definition of PN_XNUM, which meaning is the limit of program headers in
ELF structure, related to `e_phnum` field of `Elf{32,64}_Ehdr`
structures. Since these fields have identical type and seemingly
identical meaning, we can safely assume that its maximum value will be
the same on both systems.

Define PN_XNUM if it's not defined with `0xffff` value taken from
Linux and Solaris related headers.

Fixes: QTBUG-118135
