[PATCH 2/6] kbuild: rust: make command for `RUSTC_VERSION_TEXT` closer to the `CC` one

[Miguel Ojeda <ojeda@kernel.org>]

`CC_VERSION_TEXT` is defined as:

    CC_VERSION_TEXT = $(subst $(pound),,$(shell LC_ALL=C $(CC) --version 2>/dev/null | head -n 1))

Make `RUSTC_VERSION_TEXT` closer to that, i.e. add `LC_ALL=C` and `|
head -n 1` in case it matters in the future, and for consistency.

This reduces the difference in the next commit.
