Add a new shell test to verify the feature. The test covers: - Basic address remapping for user space samples. - Pipe mode coverage for piped into. - Callchain address remapping. - Consistency of output before and after injection. - Pipe mode report consistency. - Dropping of samples that leak ASLR info (physical addresses). - Kernel address remapping (utilizing a dedicated kernel-intensive VFS dd workload to guarantee continuous timer interrupts sampling flow inside kernel privilege states). - Kernel report consistency with address normalization. The test suite is hardened with global 'set -o pipefail' assertions to catch pipeline failures, stream-consuming awk processors to handle SIGPIPE signals, and a dedicated pipe output scenario validating raw 'perf inject -o -' stdout streams. Note on kernel DSO normalization in the test script: The test script deliberately normalizes all kernel DSOs to a generic [kernel] tag before diffing, as obfuscating physical kernel addresses forces perf report to occasionally shift samples between individual modules and [kernel.kallsyms] due to the lack of valid host module boundary maps. Note on ARM: Kernel-based ASLR test cases (test_kernel_aslr and test_kernel_report_aslr) are skipped on ARM architectures (aarch64 and arm*) to bypass high latency constraints (such as check_invariants() spending excessive execution time in maps__split_kallsyms() on debug builds) and symbolization inconsistencies.
