pcre2: fix gitea websearch crashing when searching for a plain string

The nixos gitea module sets MemoryDenyWriteExecute=true which requires
pcre2 to be compiled with --enable-jit-sealloc otherwise it fails with
"-48".

See https://github.com/go-gitea/gitea/issues/10840 and https://github.com/archlinux/svntogit-packages/commit/920838a6a4ca3ff466b8751d8dc4c24c5383767f
