m4/groff.m4: Improve shell code portability.
* m4/groff.m4 (GROFF_POPPLER): Improve shell code portability. Per the
GNU Autoconf manual, "The -a, -o, '(', and ')' operands are not
present in all implementations, and have been marked obsolete by Posix
2008. ...portable uses of test should never have more than four
arguments, and scripts should use shell constructs like '&&' and '||'
instead."
Continues commit 1e4d06f1dc, 24 May.
