support/scripts/apply-patches.sh: do not blindly remove *.orig files

apply-patches currently blindly removes *.orig / .*.orig files as GNU patch
by default writes these as backup files when patches only apply with fuzz.

This is unfortunate as package sources may contain files ending in .orig as
well, breaking the build.  Luckily GNU patch can be told to not write these
backup files using the --no-backup-if-mismatch option, so used that instead
of the .orig removal step.

--no-backup-if-mismatch is supported since GNU patch 2.3.8 (1997-06-17) and
busybox patch if built with CONFIG_DESKTOP, but E.G.  isn't supported by the
BSD patch, so add logic to dependencies.sh to error out if patch doesn't
support the flag.
