Subject: [PATCH] packetbeat/beater: help the GC clean up the Npcap installer
 if it's not used (#30513)

The installer bytes are released in the install case but this was accidentally
removed in #30048. This frees ~1MB of runtime memory after start up has been
completed.

(cherry picked from commit d76e44587e88f511b8a90160d54452c562de5c39)
