double inclusion of '-p' flex flag

Hi,

I see that we have included '-p' flex flag twice in the commands used
to generate the scanner files. See below:

src/backend/parser/Makefile:60:        scan.c: FLEXFLAGS = -CF -p -p
src/backend/utils/adt/Makefile:122:    jsonpath_scan.c: FLEXFLAGS = -CF -p -p
src/bin/psql/Makefile:61:       psqlscanslash.c: FLEXFLAGS = -Cfe -p -p
src/fe_utils/Makefile:43:        psqlscan.c: FLEXFLAGS = -Cfe -p -p
src/backend/utils/adt/Makefile:122:    jsonpath_scan.c: FLEXFLAGS = -CF -p -p
src/bin/psql/Makefile:61:        psqlscanslash.c: FLEXFLAGS = -Cfe -p -p

Do we need this or can the extra -p flag be removed?
