step 0f15f1ab73 [bash] Improve mawk detection (#3463) ...

* Use the all-compatible mawk `-W version` option.
  https://github.com/junegunn/fzf/pull/3313#issuecomment-1747934690.
* Run the command and not a function consistently with #3462.

The version check bash code relies on the following mawk source code,
extracted from mawk 1.3.4 20230322.

```
version.c:
18-  #include "init.h"
19-  #include "patchlev.h"
20-
21:  #define	 VERSION_STRING	 \
22-    "mawk %d.%d%s %s\n\
23-  Copyright 2008-2022,2023, Thomas E. Dickey\n\
24-  Copyright 1991-1996,2014, Michael D. Brennan\n\n"
....
30-  void
31-  print_version(FILE *fp)
32-  {
33:      fprintf(fp, VERSION_STRING, PATCH_BASE, PATCH_LEVEL, PATCH_STRING, DATE_STRING);
34-      fflush(fp);
35-
36-  #define SHOW_RANDOM "random-funcs:"

patchlev.h:
13-  /*
14-   * $MawkId: patchlev.h,v 1.128 2023/03/23 00:23:57 tom Exp $
15-   */
16:  #define  PATCH_BASE	1
17-  #define  PATCH_LEVEL	3
18-  #define  PATCH_STRING	".4"
19-  #define  DATE_STRING    "20230322"
```
