ftrace: Improve parsing for string fields
With this commit:
* The code now accepts string fields with an indentifier, instead of a
literal, for array size. This is important since commit
3087c61ed2c4("tools/testing/selftests/bpf: replace open-coded 16 with
TASK_COMM_LEN"), included in kernel 5.17, which exposes TASK_COMM_LEN
in the format.
* The code now accepts fields whose name include a digit (because that's
a valid C identifier.).
Tested: unit tests
Bug: 227677227
