[PATCH v7 3/4] elf: Remove has_interp property from arch_adjust_elf_prot()

[Mark Brown <broonie@kernel.org>]

Since we have added an is_interp flag to arch_parse_elf_property() we can
drop the has_interp flag from arch_elf_adjust_prot(), the only user was
the arm64 code which no longer needs it and any future users will be able
to use arch_parse_elf_properties() to determine if an interpreter is in
use.
