file (as in /usr/bin/file) does not honor "-L" when using mime type output.

As the ports makefile checks for shared library existance vie "file -L
--mime-type" = "application/x-sharedlib" this results in ports trying to
re-install already existing libraries.

Fix: Honestly, I'm not sure what the "&= MAGIC_MIME_TYPE" is supposed to do here,
but it actually deletes all other options from flags.

Someone with a better understanding of the code might want to check if the
code maybe was actually supposed to be "ms->flags |= MAGIC_MIME_TYPE" here?

I just added MAGIC_SYMLINK here to keep it from being deleted to fix the
problem at hand.
run file with "-L" and "--mime-type" on a symlink.

without "-L" it's ok:

ice:~>file -b --mime-type /usr/local/lib/libdb-4.2.so.2 

actual output:

ice:~>file -b -L --mime-type /usr/local/lib/libdb-4.2.so.2                   :(

expected output:

ice:~>LD_LIBRARY_PATH=/usr/obj/usr/src/lib/libmagic file -b -L --mime-type /usr/local/lib/libdb-4.2.so.2
