Fangrui Song 25863cc512 [ELF] .note.gnu.property: error for invalid pr_datasize
A n_type==NT_GNU_PROPERTY_TYPE_0 note encodes a program property.
If pr_datasize is invalid, LLD may crash
(https://github.com/ClangBuiltLinux/linux/issues/1141)

This patch adds some error checking, supports big-endian, and add some tests
for invalid n_descsz.
