wafsamba: Add compiler check for missing field initializer check
The commit cf79ee15
wafsamba: Enable warnings for missing field initializer
enabled a compiler check for warnings about missing initializers for all
developer builds. This fails with older compilers, e.g. gcc on RHEL7.
Add a waf check around adding the compiler option to avoid the failure
with older compilers.
