[OpenWrt-Devel] [PATCH] coova-chilli: fix compilation error with --enable-redir

[Xabier Oneca -- xOneca]

musl lacks `allocated` member on `struct re_pattern_buffer`
(https://fossies.org/dox/musl-1.1.20/structre__pattern__buffer.html).

Patch inspired by drkhosla @github.com/coova/coova-chilli issue #200
(https://github.com/coova/coova-chilli/issues/200#issuecomment-253497070)
