Change the initialization of "struct strbuf" changed in cbc0f81d96f (strbuf: use designated initializers in STRBUF_INIT, 2017-07-10) to omit specifying "alloc" and "len", as we do with other "alloc" and "len" (or "nr") in similar structs.

Let's likewise omit the explicit initialization of all fields in the "struct ipc_client_connect_option" struct added in 59c7b88198a (simple-ipc: add win32 implementation, 2021-03-15).

Finally, start incrementally changing the same pattern in "t/helper/test-run-command.c". This change was part of an earlier on-list version[1] of c90be786da9 (test-tool run-command: fix flip-flop init pattern, 2021-09-11).
