run-command API: rename "env_array" to "env"

Start following-up on the rename mentioned in c7c4bde (run-command
API: remove "env" member, always use "env_array", 2021-11-25) of
"env_array" to "env".

The "env_array" name was picked in 19a583d (run-command: add
env_array, an optional argv_array for env, 2014-10-19) because "env"
was taken. Let's not forever keep the oddity of "*_array" for this
"struct strvec", but not for its "args" sibling.

This commit is almost entirely made with a coccinelle rule[1]. The
only manual change here is in run-command.h to rename the struct
member itself and to change "env_array" to "env" in the
CHILD_PROCESS_INIT initializer.

The rest of this is all a result of applying [1]:

 * make contrib/coccinelle/run_command.cocci.patch
 * patch -p1 <contrib/coccinelle/run_command.cocci.patch
 * git add -u

1. cat contrib/coccinelle/run_command.pending.cocci

   - E.env_array
   + E.env

   struct child_process *E;
   @@
   - E->env_array
   + E->env

I've avoided changing any comments and derived variable names here,
that will all be done in the next commit.
