[MemProf] Add missing header to list of installed headers. (#79413)

There were buildbot failures when running memprof tests:

I suspect the failure is because when build with
-DLLVM_ENABLE_RUNTIMES=compiler-rt -DCOMPILER_RT_BUILD_SANITIZERS=OFF,
the headers sanitizer/allocator_interface.h and
sanitizer/common_interface_defs.h
are not copied to the build tree, and not installed.
But in the failed memprof tests,
sanitizer/allocator_interface.h or sanitizer/memprof_interface.h is
included.

This patch adds sanitizer/allocator_interface.h and
sanitizer/memprof_interface.h to memprof headers if
COMPILER_RT_BUILD_SANITIZERS is false.
