graphics/zathura links against sysutils/file

[abi]

Hello again!

graphics/zathura has sysutils/file in LIB_DEPENDS for libmagic.so 
However we already have this lib in base since FreeBSD 7.0

zathura links to external one and somehow confuses pkg. pkg autoremove 
suggests to remove sysutils/file, breaking zathura.

After I removed sysutils/file from port Makefile, it linked to the base lib.

The thing that confuses me is that in poudriere zathura links correctly, 
but 11 jail there is rather outdated.
