copy.mk: Revert change as it does not handle * PLIST entries

[th0ma7]

Motivation: A but was introduced in an earlier PR #5018 where PLIST entries with * are not being handled anymore.
Linked issues: #5044 (comment)

Checklist

• Build rule all-supported completed successfully
• Package upgrade completed successfully
• New installation of package completed successfully

With d442ce2 commit I tested succesfully:

• bazarr : Uses PLIST.auto
• python310 (update to 3.10.1) : Uses * plist entries through cross/pip

Mandatory required for releasing

• python310 - 3.10.1-6
• bazarr - 1.0.2-3

@hgy59 quick testing shows that this line is the culprit. Can you double-check on your side?

[th0ma7]

@hgy59 a second pair of eye would be appreciated as I am reverted a one-liner from your previous PR. On my side testing looked good and ready to merge.

I'll be merging right away as this blocks a few pending packages to be published + I'll rebase #5050 which triggers the issue which should provide another set of confirmation that all is good.
