[PATCH 2/4] groff: fix native perl path

[Hongxu Jia <hongxu.jia@windriver.com>]

Build groff on a machine with /bin/perl, it gave an error at rootfs time:
...
|ERROR: Unable to install packages. Command 'tmp/sysroots/x86_64-linux/
usr/bin/smart --quiet --data-dir=tmp/work/qemux86-poky-linux/core-image
-minimal/1.0-r0/rootfs/var/lib/smart install -y groff@i586 run-postinsts@all
packagegroup-core-boot@qemux86 perl@i586' returned 1:
|error: Can't install groff-1.22.3-r1@i586: no package provides /bin/perl

ERROR: Function failed: do_rootfs
...

Previously (From OE-Core rev: 79fc557683d4eeadaebeb00dfba53762956e4910 and
103d668cece420447c12987119459ebd49c208df), we manually edit perl scripts
with replacing '/usr/bin/perl' or '/bin/perl' with '/usr/bin/env perl'.
If new perl scripts added after groff upgraded, we have to manually
do the modification on them.

The groff did the above modification according the value of PERL,
so we set it correctly could fix it.

We also add perl and ghostscript to groff DEPENDS, because it requres
perl >= v5.6.1 and ghostscript, see README:
...
 52 Depending on your requirements, you may need at least some of the
 53 following tools to build `groff' directly from its source:
 54
 55   perl >= v5.6.1 (see macro GROFF_PERL in file `m4/groff.m4')
 56   ghostscript
...
