add -flto=thin to mac aarch64 build cflags for ez 10% gain (#469) 
Adds somewhere between 5-10% improvement to wall time.

I've ran all tests, booted several fakeships and comets with this
installed, and all seems to work properly.

Mac x86 is coming, I just don't have access to an intel mac right now
[but soon...].
Linux will come later once I figure out some bugs.

The following is time to boot a fakeship from a brass pill:
```
Without LTO:
________________________________________________________
Executed in  180.46 secs    fish           external
usr time   17.83 secs    0.10 millis   17.83 secs
sys time    0.23 secs    1.86 millis    0.23 secs


With LTO:
________________________________________________________
Executed in  164.87 secs    fish           external
usr time   15.65 secs    0.12 millis   15.65 secs
sys time    0.19 secs    1.94 millis    0.19 secs
```
180/164 -> 1.09

## Brass pill boot:

x86 linux without lto: ~140s
x86 linux with    lto: ~128s

~ 8.6% improvement - note we may be able to squeeze a bit more out if we
can
apply `-flto` to all dependencies and not just urbit binaries. This is
currently
an issue for x86 linux though due to some weird uninvestigated behavior
with
libsigsegv

## For those curious, the following hints at what was inlined
