[PATCH] git.c: two memory leak fixes

[Alexander Kuleshov <kuleshovmail@gmail.com>]

This patch provides fixes for two minor memory leaks in the
handle_alias function:

1. We allocate memory for alias_argv with the xmalloc function call,
after run_command_v_opt function will be executed we no need in this
variable anymore, so let's free it.

2. Memory allocated for alias_string variable in the alias_lookup function,
need to free it.
