Change subject: send uname() release as IV_PLAT_VER= on non-windows versions
......................................................................
send uname() release as IV_PLAT_VER= on non-windows versions
This is highly system specific, as the content of the uname()
structure elements is not specified very well - uname(3) says:
release Release level of the operating system
which translates to "IV_PLAT_VER=13.3-RELEASE-p6" (FreeBSD) or
"IV_PLAT_VER=22.6.0" (macOS) - the latter being the "Mach Kernel
version", not what Apple calls the OS.
It's still useful if a server operator needs to keep track of
client versions (and the GUI does not set the corresponding
environment variable, which neither Tunnelblick nor NM do).
v2: manpage amendments
v3: whitespace
v4: reword manpage
