Update install dir for dscheck_VMwareGuestInfo

This patch amends 9efe9a2f1523e25bbd88e2b8952f0cccf061e0bb and updates
the install directory for dscheck_VMwareGuestInfo to /usr/bin as
/usr/local/bin is not in the PATH when systemd runs
cloud-init-generator, which uses ds-identify to determine what
datasources are available.
