[OE-core] [oe-core][PATCH] gzip; update ptest package dependencies

[Trevor Gamblin]

From: Trevor Gamblin <trevor.gamblin at windriver.com>

gzip-ptest skips the following tests on core-image-sato builds:

- zgrep-context
- zdiff
- zgrep-signal

The same tests pass on core-image-sato-sdk builds. This is due to
the use of busybox tool variants on core-image-sato (zgrep-context,
zdiff) and the absence of the perl and perl-ptest packages
(zgrep-signal). This patch adds the dependencies needed for all
three tests.
