perf build: Prefix SCRIPTS with output directory to fix continuous rebuilds

perf build: Prefix SCRIPTS with output directory to fix continuous rebuilds

In Makefile.perf, ALL_PROGRAMS includes SCRIPTS (perf-archive,
perf-iostat). However, unlike PROGRAMS and DLFILTERS, SCRIPTS was not
prefixed with $(OUTPUT).

During out-of-tree builds (or when O= is specified), Make checked for the
unprefixed target 'tools/perf/perf-archive'. Since the actual script was
installed into $(OUTPUT)perf-archive, Make concluded the target was
missing and continuously re-executed the script installation rule on every
single incremental build.

Prefix SCRIPTS with $(OUTPUT) and update the static pattern rule to ensure
Kbuild correctly tracks generated script prerequisites during incremental
builds.
