LLVM: Do not map read-only data sections as executable.

As described in full details in the associated bug, LLVM will
map read-only data sections with READ+EXECUTE permissions by
default. Unfortunately, this makes certain tests fail on Fuchsia,
because this platform is very strict regarding the EXECUTE mapping
flag.

This CL fixes the issue by ensuring that non-code sections are
only mapped with the READ permission instead.

An upstream LLVM bug has been sent to https://reviews.llvm.org/D78574
