Use the same compiler options for xrpl.libxrpl and all its submodules

* Resolves an issue introduced by XRPLF#5111, which inadvertently removed the
  -Wno-maybe-uninitialized compiler option from those modules. This
  resulted in new "may be used uninitialized" build warnings, first
  noticed in the "protocol" module. When compiling with derr=TRUE, those
  warnings became errors, which made the build fail.
