[PATCH v2] ldso: fix unused variable warning

This fixes the following warning when SUPPORT_LD_DEBUG_EARLY is not enabled:

ldso/ldso/ldso.c: In function '_dl_get_ready_to_run':
ldso/ldso/ldso.c:754:16: warning: unused variable 'tmp' [-Wunused-variable]

This was introduced with commit 94cc6edb (ldso: Rework global scope handling
and symbol lookup mechanism).

v2: We need the old value of l_tls_initimage for the debug message, so instead 
    of removing 'tmp', mark it with the 'unused' attribute (Filippo 
    Arcidiacono)
