Only try to reset crashkernel for osbuild during package install 

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2060319

Currently, kexec-tools tries to reset crashkernel when using anaconda to
install the system. But grubby isn't ready and complains that,
  10:33:17,631 INF packaging: Configuring (running scriptlet for): kernel-core-5.14.0-70.el9.x86_64 1645746534 03dcd32db234b72440ee6764d59b32347c5f0cd98ac3fb55beb47214a76f33b4
  10:34:16,696 INF dnf.rpm: grep: /boot/grub2/grubenv: No such file or directory
  grep: /boot/grub2/grubenv: No such file or directory

We only need to try resetting crashkernel for osbuild. Skip it for other
cases. To tell if it's package install instead of package upgrade, make
use of %pre to write a file /tmp/kexec-tools-install when "$1 == 1" [1].
