The home directory (/home/git) has the correct selinux context (user_home_t) as far as I can tell and I've run 'restorecon -Rvv' anyway, just to be sure.  gitosis works by calling a system binary, gitosis-serve, which lives in /usr/bin/ and has the type of 'bin_t'
What is your verison of selinux-policy?

# rpm -q selinux-policy selinux-policy-targeted

gitosis-serve should have the following context:

# ls -Z /usr/bin/gitosis-serve
-rwxr-xr-x. root root system_u:object_r:gitosis_exec_t:s0 /usr/bin/gitosis-serve
