daemon: Fix redundant redeclaration warning

  CC     pulseaudio-dumpmodules.o
daemon/dumpmodules.c:93:27: warning: redundant redeclaration of ‘lt__PROGRAM__LTX_preloaded_symbols’ [-Wredundant-decls]
/usr/include/ltdl.h:106:36: note: previous declaration of ‘lt__PROGRAM__LTX_preloaded_symbols’ was here

the declaration is provided by ltld.h of libtool since version 2.4, require the 2.4 instead of 2.2
