Some benchmark suites contain test cases that have nonreproducible behaviour. This is mostly caused by relying on "now" when dealing with dates or timestamps, instead of using a fixed moment. (A notorious example is the crypto-aes.js test case of the sunspider bechmark suite, where the heap memory consumption can vary between 34K-41K heap because of using `(new Date()).getTime()`.) This commit renames the jerry-minimal command line tool to jerry-test (to better reflect its purpose) and adds extra code, which intercepts some calls to libc (`gettimeofday`, `rand`) and pins their results to some fixed values. This makes the tool useless in a general case but ensures stable results when benchmarking -- for which it is mostly used. As a side effect, the commit also changes jerry-libc by making all libc functions weak symbols to allow their override from application code.
