Subject: [PATCH] Fix potential use of uninitialized pipe array

Conflict:NA
Reference:https://github.com/rpm-software-management/rpm/commit/bff65aad8af719542c7b0c6429e09223c014a909

We only call pipe(2) after the script is written to disk so if the
latter fails, the array will be left uninitialized and subsequently read
after skipping to the exit label.  Fix by initializing it.

Found by Coverity.

Fixes: RHEL-22604
