ksupport: Remove unused sections from linker script [nfc]
...
We no longer build ksupport.ld in a position-independent fashion, and
the reference to the ld.bfd _GLOBAL_OFFSET_TABLE issue was just a
distraction

Upgrade to LLD 14
...
Previous linker versions had inserted some zero padding bytes
between the ELF headers and the first section, but LLD 14 does
not anymore.
Hard-coding the offset of the first section in ksupport.elf
manually isn't ideal; we should probably parse the ELF program
headers instead when first setting up the kernel CPU.

This should give even only mildly technical users a
chance to figure out what's going on, which empirically
is not the case for a plain Exception(LoadFault) without
further context.

ksupport: fix rpc, cache signature (FFI)
...
The reason of the borrow stuff is explained in M-Labs/artiq-zynq#76 (artiq-zyna repo).
As for `cache_get()`, compiler will perform stack allocation to pre-allocate the returned structure, and pass to cache_get alongside the `key`.
However, ksupport fails to recognize the passed memory, so it will always assume the passed memory as the key.
