i18n: Use %s placeholders in wp-admin/includes/file.php

[ramiy]

One more translation string that uses file names and constants in translation string.

See the attached screenshot.

The attached patch replaces them with %s placeholders.

Old Strings:

• The uploaded file exceeds the upload_max_filesize directive in php.ini.
• The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.

New Strings:

• The uploaded file exceeds the %1$s directive in %2$s.
• The uploaded file exceeds the %s directive that was specified in the HTML form.

[ramiy]

We should consider replacing in php.ini not only with in %2$s but with in %2$s file.
