bitbake: fetch/git: Fix uri in git checkstatus

Pass proper repository url without arguments after a semicolon.

Executing checkuri on a rule with git repository in SRC_URI does
not report errors when working offline because wrong repository
url is passed to the ls-remote command. For example
"bitbake -c checkuri glibc" command executes:
"git -c core.fsyncobjectfiles=0 ls-remote git://sourceware.org/git/glibc.git;branch=release/2.21/master"
command in a shell subprocess to determine if url is valid.
Shell subprocess executes in fact 2 commands:
"git -c core.fsyncobjectfiles=0 ls-remote git://sourceware.org/git/glibc.git"
and
"branch=release/2.21/master"

First one returns 127 or 128 depending on error but second one
returns 0 because it is just env variable setup. Therefore we're not catching
connection error.
