dev-util/bazel: >=glibc-2.30 and gcc:11 compatibility fixes

Ensure that versions 0.22.0, 0.24.1 and 0.27.2 are also patched so as not to
conflict with glibc's gettid(2) function. Have all versions include the
<limits> header, where required, for compatibility with gcc:11. Revise the
dubious test for the presence of ccache so as to consider the value of
FEATURES instead. Drop version 2.0.0 in favour of 2.0.1.
