Neel Natu 874a6e051b After r267897 brought in a new version of file/libmagic, a filesystem image
is identified as "DOS/MBR boot sector" as opposed to "x86 boot sector".

This trips up vmrun.sh when using the new file(1) and makes it want to boot
into the installer instead.

Fix this by just looking for "boot sector" instead.
