build: allow to run SCYLLA-VERSION-GEN utility out of source

Browse Source 
This change allows to invoke the script in out-of-source
builds: `git log` now uses `-C` option with the directory
containing the script.

Also, the destination path can now be overriden by providing
`-o|--output-dir PATH` option. By default it's set to the
`build` directory relative to the script location.

Usage message is now shown, when '-h|--help' option is
specified.

USAGE=$(cat <<-END
Usage: $(basename "$0") [-h|--help] [-o|--output-dir PATH] -- generate Scylla version and build information files.
Options:
-h|--help show this help message.
-o|--output-dir PATH specify destination path at which the version files are to be created.
By default, the script will attempt to parse 'version' file
in the current directory, which should contain a string of
'\$version-\$release' form.
Otherwise, it will call 'git log' on the source tree (the
directory, which contains the script) to obtain current
commit hash and use it for building the version and release
strings.
The script assumes that it's called from the Scylla source
tree.
The files created are:
SCYLLA-VERSION-FILE
SCYLLA-RELEASE-FILE
SCYLLA-PRODUCT-FILE
By default, these files are created in the 'build'
subdirectory under the directory containing the script.
The destination directory can be overriden by
using '-o PATH' option.
