libc: fix environ symbol by syncing getenv.c with FreeBSD
The environ symbol can't be found by rtld with libc symbol versioning.
On Release 4.2, readelf produces this output, indicating "environ" is
classified as an object:
> readelf -a /lib/libc.so.8 | grep environ
00000032af20 01ed00000006 R_X86_64_GLOB_DAT 0000000000351380 environ + 0

1636: 0000000000351380 8 OBJECT GLOBAL DEFAULT 24 environ
After this commit:
> readelf -a /lib/libc.so.8 | grep environ
000000330c78 000700000006 R_X86_64_GLOB_DAT 0000000000000000 environ + 0

1660: 0000000000000000 0 NOTYPE GLOBAL DEFAULT UND environ
The above is the desired output.

Update some more symbols maps for libc
This continues the work towards versioning libc. I found that a wchar
function, open_wmemstream(), had a prototype but was not implemented on
DragonFly (but it is on FreeBSD) so I filtered it out with #if 0 block.
