meson: Increase stack size limit for sanitizer builds

When building with "CC=clang", "-Db_sanitize=address,undefined", and
"-Dbuildtype=debug", the following error occurs:

    ../src/conf/nwfilter_conf.c:2190:1: error: stack frame size of 10616
    bytes in function 'virNWFilterRuleDefFixup' [-Werror,-Wframe-larger-than=]
    virNWFilterRuleDefFixup(virNWFilterRuleDef *rule)
    ^
    1 error generated.

Enforcing stack frame only makes sense on normal builds when stack usage
is deterministic.
