ldlinux: Match arg types to function prototypes

Change the types of some local variables to match the type in the
function prototypes, thereby avoiding the following warnings,

ldlinux.c:132:2: warning: pointer targets in passing argument 2 of ‘syslinux_getadv’ differ in signedness
../../../com32/include/syslinux/adv.h:55:22: note: expected ‘size_t *’ but argument is of type ‘int *’
ldlinux.c:132:6: warning: assignment discards qualifiers from pointer target type
ldlinux.c:156:3: warning: pointer targets in passing argument 1 of ‘load_kernel’ differ in signedness
ldlinux.c:58:13: note: expected ‘const char *’ but argument is of type ‘uint8_t *’
