debugging: add support for non-glibc targets for debugging

This relaxes the ELF mem_image handling and subsequently enables the VDSO
support for non-glibc targets.  The primary need for the restriction was the
use of the `__GLIBC_PREREQ` macro.  If it is undefined, assume that the glibc
pre-requisite is unavailable.  This allows building the debugging_internal
target on musl targets.
