lang/gcc11-devel: Fix Address sanitizer
Software compiled with -fsanitize=address fails to run with the error
message "ASan runtime does not come first in initial library list; you
should either link runtime to your application or manually preload it
with LD_PRELOAD".
This commit fixes the issue by ignoring the [vdso] loaded shared library
instead of linux-vdso.so.
