avcodec/allcodecs: Don't include libx264 twice in the list of codecs

Since a247ac640df3da573cd661065bf53f37863e2b46, allcodecs.c contained
two lines that matched the regex used by find_filters_extern in
configure; as a result, libx264 appeared twice the list of codecs
(if enabled).

Fix this by using only one matching line by adding a preprocessor define
for the part that differed in the two old lines: The const qualifier.
