block/dmg: Ignore C99 prototype declaration mismatch from <lzfse.h>
When liblzfe (Apple LZFSE compression library) is present
(for example installed via 'brew') on Darwin, QEMU build
fails as:
Has header "lzfse.h" : YES
Library lzfse found: YES
Dependencies
lzo support : NO
snappy support : NO
bzip2 support : YES
lzfse support : YES
zstd support : YES 1.5.2
User defined options
dmg : enabled
lzfse : enabled

This issue has been reported in the lzfse project in 2016:
https://github.com/lzfse/lzfse/issues/3#issuecomment-226574719
Since the project seems unmaintained, simply ignore the
strict-prototypes warning check for the <lzfse.h> header,
similarly to how we deal with the GtkItemFactoryCallback
prototype from <gtk/gtkitemfactory.h>, indirectly included
by <gtk/gtk.h>.
