1745daea0f meson: support clang built from git
get_clang_ver fails if clang is built from scratch.

Teach get_clang_ver to recognize the clang version even for clang built
from git.

These are the tests I ran:

	# /usr/local/bin/clang --version
	clang version 18.0.0git (https://github.com/llvm/llvm-project.git c458f928fad7bbcf08ab1da9949eb2969fc9f89c)
	# meson-scripts/get_clang_ver /usr/local/bin/clang
	18.0.0

	# /usr/bin/clang --version
	clang version 17.0.6 (CentOS 17.0.6-5.el9)
	# meson-scripts/get_clang_ver /usr/bin/clang
	17.0.6

00cd15a3ae build: properly detect clang version in Ubuntu
Some distro may add their own prefix to the version string of clang, for
example in Ubuntu:

 $ clang --version
 Ubuntu clang version 17.0.5 (1ubuntu1)
 ...

That triggers the following meson error during the setup phase:

 meson.build:25:44: ERROR: String '' cannot be converted to int

Change the regexp used to evaluate the clang version to avoid this
build failure.
