Ian Rogers 190c454638 perf test: Add inject ASLR test 
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.
