scripts: disable tcmalloc to support valgrind memcheck

[neverchanje]

Now we are able to use:

$ ./run.sh build --disable_gperf 

to disable tcmalloc, and we can then perform valgrind memcheck in builder/bin/<test_name>, like

$ cd builder/bin/dsn_nfs_test
$ valgrind --tool=memcheck ./dsn_nfs_test config.ini

为什么不直接把命令叫做ENABLE_GPERF，偏要叫做WITH_VALGRIND?

[neverchanje]

原本是准备叫 --disable_gperf，但是我感觉作为 shell 工具，叫 --with_valgrind 更易用更直观，当然你觉得名字一致比较重要就可以改

[shengofsun]

我觉得名字一致比较重要：用了某个命令，到底干了什么事情，这样比较直观的。另一个原因是，我想禁用gperf的原因，不一定是要开valgrind, 也可能就是想单纯的对比下性能。

你可以在--disable_gperf的help里面，或者一些文档里面说明"you may want to use this option when you want to run valgrind"之类的。

好的

[shengofsun]

另外我看你把format子命令删了。这样的话，也可以顺手把scripts/linux/format.sh也一起删了。

[neverchanje]

已删
