osutil: export a "getfstype" method

This patch exports the "getfstype" method. So we can use it to enable
hardlinks for known safe filesystems.

The patch was tested manually via debugshell on a Linux system.
"mercurial.osutil.getfstype" works as expected. It's hard to mount
filesystem on user-space easily. I will add a test for real hardlink support
to indirectly test this patch, after turning on real hardlinks support for
certain whitelisted filesystems.

# An example WSGI for use with mod_wsgi, edit as necessary

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()

# enable demandloading to reduce startup time
