[gdb/symtab] Fix uninitialized memory in buildsym_compunit::finish_block_internal
When running test-case gdb.dwarf2/per-bfd-sharing.exp with target board stabs,
gdb either segfaults or asserts due to reading uninitialized memory, allocated
here in buildsym_compunit::finish_block_internal:
...
ftype->set_fields
((struct field *)
TYPE_ALLOC (ftype, nparams * sizeof (struct field)));
...
Fix this by using TYPE_ZALLOC instead.
Tested on x86_64-linux.
