[PATCH xawtv3 2/2] Use `pclose` to close file-pointer created with `popen`

[Jeremy Sowden <jeremy@xxxxxxxxxx>]

gcc reports:

  x11/man.c: In function 'man':
  x11/man.c:106:5: warning: 'fclose' called on pointer returned from a mismatched allocation function [-Wmismatched-dealloc]
    106 |     fclose(fp);
        |     ^~~~~~~~~~
  x11/man.c:69:10: note: returned from 'popen'
     69 |     fp = popen(line,"r");
        |          ^~~~~~~~~~~~~~~

and the popen(3) man-page states:

  The return value from popen() is a normal standard I/O stream in all respects
  save that it must be closed with pclose() rather than fclose(3).
