Before this patch, it missed this in `curl/curl.h`:
```c
# define __has_declspec_attribute(x) 0
```
After this patch:
```
test 1167...[Verify curl prefix of public symbols in header files]
/usr/bin/perl -I. -I. returned 1, when expecting 0
1167: exit FAILED
== Contents of files in the log/14/ dir after test 1167

FAIL 1167: 'Verify curl prefix of public symbols in header files' source analysis

This avoids mistaking symbols with their numeric value when using
certain C preprocessors which output these numeric values at the
beginning of the line as part of an expression.
Seen on OpenBSD 7.5 + clang.
Example `test1167.pl -v` output, before this patch:
```
Source: cpp /home/runner/work/curl/curl/tests/../include/curl/curl.h
Symbol: 20000
Line #3835: 20000 + 142,
[...]
Bad symbols in public header files:
20000
[...]
```

It is hard to name the scripts sensibly. Lots of them are similarly
named and the name did not tell which test that used them.
The new approach is rather to name them based on the test number that
runs them. Also helps us see which scripts are for individual tests
rather than for general test infra.
