build: Use #ifdef to check for #defines

Browse source 
for example, in case HAVE_MEMFD is #undef, checking with #if HAVE_MEMFD
gives a warning (gcc 5.4.1, Ubuntu)

pulsecore/shm.c: In function 'sharedmem_create':
pulsecore/shm.c:208:5: warning: "HAVE_MEMFD" is not defined [-Wundef]
 #if HAVE_MEMFD

use #ifdef or #if defined() to check for presence of a #define
