Address jgh notes re OpenSSL
* `/usr/local` is fair, on Linux, but I deliberately picked something
specific to OpenSSL to make the context clear and limit bad
interactions with other locally-installed software.
* `RPATH` and `RUNPATH` are not the same and are deeply twisty in their
interactions.
<https://blog.qt.io/blog/2011/10/28/rpath-and-runpath/> is a decent
summary.

openssl: use += for LDFLAGS, drop env PC docs
Using `LDFLAGS=` instead of `LDFLAGS+=` will stomp over an earlier
setting of LDFLAGS, and the DMARC support is now further up in
`src/EDITME`, thus likely to get stomped upon.
Rather than continue to document using `PKG_CONFIG_PATH` via env, the
in-Local/Makefile support has been around for a little while now, so go
ahead and make that the only way we suggest here.
Add a mention of _why_ we use both `USE_OPENSSL_PC` and `LDFLAGS`.

Fix dec64table[] OOB read in b64decode()
Possible values for y at this point are 0..255. However, dec64table[]
only has 128 entries and hence valid indexes are 0..127. The values of
y greater than 127 trigger out of bounds read. As dec64table[] is in
the data segment, the OOB access is not detected by tools as valgrind or
ASAN. This adds a check to ensure y is less than or equal to 127, just
like in other cases where dec64table[] is accessed.
Note that removal of the y == 0 condition is not a problem, as
dec64table[0] == 255, so the second part of the condition is true.
