Turn MALLOC_PRODUCTION into a regular src.conf(5) option

For historical reasons, defining MALLOC_PRODUCTION in /etc/make.conf has
been used to turn off potentially expensive debug checks and statistics
gathering in the implementation of malloc(3).

It seems more consistent to turn this into a regular src.conf(5) option,
e.g. WITH_MALLOC_PRODUCTION / WITHOUT_MALLOC_PRODUCTION. This can then
be toggled similar to any other source build option, and turned on or
off by default for e.g. stable branches.

Set LG_VADDR to 48 on RISC-V.

The Sv48 PTE format is the largest currently defined address space for
RISC-V. It makes no sense to define a larger size and doing so (at
least for 64-bits) forces rtrees down a slow path.

Revert r354605: Update jemalloc to version 5.2.1.

Compilation fails for non-llvm-based platforms.
