custom perf & dtrace invocation support

Support is now added for passing custom scripts to perf & dtrace using the -c argument. This enables correlating various interesting perf metrics like branch-misses, cache-misses, topdown-fetch-bubbles or anything else listed by your system's perf list output.

example:

cargo flamegraph -c "record -e branch-misses -c 100 --call-graph lbr -g"

Binaries for this release are provided for x86_64 linux.
