Makefile: fix OPENSBI_VERSION_GIT build with submodules

Browse Source 
When building OpenSBI via a submodule, OPENSBI_VERSION_GIT can be left
unset in case '.git' isn't a dir. This is the case when building OpenSBI
as a QEMU submodule:

$ cat .git
gitdir: ../../.git/modules/roms/opensbi

As a result, building OpenSBI tag v1.5.1 in QEMU will result in a binary
that will have "OpenSBI v1.5" as a banner.

Use "git rev-parse --git-dir" instead of checking if '.git' is a dir to
detect if the current dir is a git repo.
