[gdb/testsuite] Require DW_LNE_end_sequence
The dwarf standard requires that every line number program sequence ends
with a DW_LNE_end_sequence instruction.
Enforce this in the dwarf assembler for the last sequence in a line number
program (we have no means to enforce this for earlier sequences), and fix a
few test-case that don't have it.
Tested on aarch64-linux.
