meson: Allow undefined symbols when sanitizers are enabled

Browse Source 
When enabling sanitizers, clang adds some function symbols when
instrumenting the code. The exact names of those functions are an
implementation detail and should therefore not be added to any
syms file. This patch prevents build failures due to those symbols
not present in the syms file when building with sanitizers enabled.
