[PATCH] builtin/apply.c: make a file local symbol static

[Ramsay Jones <ramsay@ramsayjones.plus.com>]

Commit dddaaab62 ("apply: convert root string to strbuf", 24-09-2015)
converted a <char *str, int len> combination of variables into a
single 'struct strbuf' variable. In doing so, it unintentionally
increased the visibility of the variable. In order to reduce the
visibility to file local, add the static keyword to the declaration
of the 'root' symbol.

Hi Jeff,

If you need to re-roll your 'jk/war-on-sprintf' series, could you
please squash this into the relevant patch.

Thanks!

ATB,
Ramsay Jones
