Fix ports-mgmt/portfind string management/searching issues
Makefile:
Bump `PORT_REVISION` for the change.
portfind.c:
get_release(..): The function was incorrectly modifying a pointer that wasn't the original calloc'ed pointer, tripping asserts when MALLOC_PRODUCTION wasn't enabled in jemalloc [*]. - Use one temporary buffer (`release`) instead of two (`release` and `version`). - Improve temporary memory idiom for managing memory used with sysctlbyname(3) by first checking the length, mallocing the buffer, then filling it with a second call to sysctlbyname(3). - Use strchr(3) instead of handrolling it in a while-loop and to avoid the improper free(3) of the memory allocated for `release`. main(..): - Use asprintf instead of calloc + sprintf. - Use constant `pasting` with `INDEX_FILE` instead of passing it in to asprintf(3). - Fix error message when unable to open `INDEX_FILE`.
