delocate: remove the need to demangle local variables

We need to demangle because the backing storage for a delocated BSS
symbol is declared static. The compiler seems to be always give it a
C++-mangled name. But we relied on those names to infer the names of the
bss_get functions that the rest of the code wanted.

Instead, if we make the backing storage non-static, we get the name we
want. Ideally we would avoid having to extract those names (see
https://boringssl-review.googlesource.com/c/boringssl/+/70849), but
faking the linker script behavior in delocate seemed tricky, so I opted
to do this and then we can finish up the linker script version later.

While I'm here, prefix the underlying names with 'bcm_' so we're not
squatting as much of the namespace.
