e1a9513783 Move few policies from tsan to All section. 
munmap is widely used by sanitizer, but it
probably works for Asan/Msan because it's enabled
by unrelated Allow* call.

Move mprotect to shared part as well. It will be
needed for compress_stack_depot.

befdb09597 Link more complex test cases dynamically 
Linking glibc in fully static mode is mostly unsupported. While such binaries
can easily be produced, conflicting symbols will often make them crash at
runtime. This happens because glibc will always (try to) load some dynamically
linked libraries, even when statically linked. This includes things like the
resolver, unicode/locale handling and others.

Internally at Google, this is not a concern due to the way glibc is being built
there. But in order to make all of our tests run in the open-source version of
this code, we need to change strategy a bit.

As a rule of thumb, glibc can safely be linked statically if a program is
resonably simple and does not use any networking of locale dependent
facilities. Calling syscalls directly instead of the corresponding libc
wrappers works as well, of course.

This change adjusts linker flags and sandbox policies to be more compatible
with regular Linux distributions.

Tested:
- `ctest -R '[A-Z].*'` (all SAPI/Sandbox2 tests)

36d0f928c6 Apply page offset during stack unwinding/symbolization 
This fixes a couple of tests in the open source version of the code.
Internally, since we are using a different ELF loader, the page offset
will always be zero. Hence we never notices this was broken.

dc03c38df1 Enable stack traces on AArch64 
Note that `//sandboxed_api/sandbox2:stack_trace_test` may still fail for
unrelated reasons, as we are linking libc statically, which is brittle. A
follow-up change will fix this.
