On Solaris getpass() returns at most 8 characters which cripples the
credential reading for accounts using longer passwords. The alternate
function getpassphrase() was introduced in SunOS 5.6 and will return
up to 256 characters.
Ensure that git_terminal_prompt uses the more able function when
building on Solaris.

Hi Jeff and Junio,
I considered making this minor change a few different ways but settled
on this as it seemed (to my eye) to most closely adhere to the way
other such things were done in the compatibility code. I'm entirely
open to modifying this if it's felt that there is a clearer/cleaner
way to do it.
I'd even considered making the function swap generic enough to be
driven by the build system. That seemed over the top though, given
that most systems either have a decent getpass() or don't use this
code path at all.
I've also briefly dabbled with getting Solaris to simply use the
HAVE_DEV_TTY code path but the terminal echo stuff hasn't worked
nicely for me just yet. (It reads the password with nothing echoed
but then displays the string after reading the newline.) This might
still be a better approach in the future, but for now, having long
password reading capability will still be a benefit to users on this
platform.
Thanks
