Log message:
Update to sessreg-1.0.3.  Remove patch-aa, as the portability fix
is integrated.  Also, replace per-OS preprocessor directives
for #define NO_UTMP in sessreg.h with NO_COLON_ZERO_IN_UTMP.
Please see Makefile and patch-ab for clarification.  While here,
add CONFIGURE_ARGS+=--localstatedir=${VARBASE:Q} and BUILD_DEFS+=VARBASE,
as this package definitely uses it.
