gdb: print unknown part of flag enum in hex
When we print the "unknown" part of a flag enum, it is printed in
decimal. I think it would be more useful if it was printed in hex, as
it helps to determine which bits are set more than a decimal value.
gdb/ChangeLog:
* valprint.c (generic_val_print_enum_1): Print unknown part of
flag enum in hex.
gdb/testsuite/ChangeLog:
* gdb.base/printcmds.exp (test_print_enums): Expect hex values
for "unknown".
