aarch64: ld: Fix scanning of GNU properties for AARCH64_FEATURE_1_AND

Fixes [1]. Previously iteration over GNU properties of an input file
could stop before reaching GNU_PROPERTY_AARCH64_FEATURE_1_AND which
would result in incorrect inference of properties of the output file.

In the particular use case described in [1], the memory seal property
GNU_PROPERTY_MEMORY_SEAL with number 3, if present in the input file,
prevented reading information from GNU_PROPERTY_AARCH64_FEATURE_1_AND
property due to filtering by property number.
