[libcxx] [ci] Don't use the "-s" flag in LLVM_LIT_ARGS

The "-s" flag gives a nice visual progress bar when running lit,
which is useful when running interactively, but makes the log
output near illegible.

Additionally, by omitting "-s", the CI log becomes much more useful,
as it prints the outcome of each individual test (by printing
"PASS" or "UNSUPPORTED" or "XFAIL" for each one), making it
clearer which tests were executed and which were skipped.
