Disable RTLD_DEEPBIND when compiling with AddressSanitizer (-fsanitize=address).
The AddressSanitizer doesn't support RTLD_DEEPBIND resulting in
erratic errors when deinitializing phar module and possibly others.
Clang use __has_feature() macro to indicate compilation with
AddressSanitizer while gcc uses __SANITIZE_ADDRESS__ define.
Fixes bug #73677.
