include/mountutils.h: fix LSMT_ROOT definition

Commit
ded434a63f3eee7fd7805b18d6c9bb912016c3c8 ("include/mount-api-utils:
add statmount and listmount") introduce a fallback definition for the
LSMT_ROOT defined, but a small typo makes this fallback definition
ineffective:

 #ifdef LSMT_ROOT
 # define LSMT_ROOT ...
 #endif

Should obviously have been:

 #ifndef LSMT_ROOT
 # define LSMT_ROOT ...
 #endif
