Title: Fix datadir.mkpath for bottled percona-server formula

Moved datadir.mkpath (i.e. the creation of var/mysql) to the post_install function. This ensures that the path is created with both compiled and bottled percona-server.

Without this fix when this formula is bottled it errors on install.
