elf: Enable TLS descriptor tests on aarch64
The aarch64 uses 'trad' for traditional tls and 'desc' for tls descriptors, but unlike other targets it defaults to 'desc'. The gnutls2 configure check does not set aarch64 as an ABI that uses TLS descriptors, which then disable somes stests. Also rename the internal machinery fron gnu2 to tls descriptors. Checked on aarch64-linux-gnu. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
