Some of the spdmlib crypto functions return 'false' in
functions that return a pointer to indicate a null
return. false is mapped to FALSE to cover other usages
to return a boolean value.
Add -Wno-non-literal-null-conversion for CLANGPDB and
CLANGDWARF to ignore these types of errors from CLANG
builds within this one library build that uses the
spdmlib git submodule.
