fix build with unmodified mingw32

Close #5867

V4L2_FIELD_INTERLACED_BT was introduced in v2.6.25-3581-g26d507f
Check for headers from last supported kernel

With libcompat installed (into $(prefix)/lib/vlc/ or whatever), libtool
will actually pull only needed functions from the static import library
libcompat.a. Previously, it would copy every compat functions into
every VLC binaries. This should shrink plugins a bit.

The patches are not necessary anymore (merged) and the last issue,
setlocale is not used anymore, for uselocale.

Selecting 'Custom' for cache level in simple preferences should leave current
settings alone.  Custom levels are set in advanced preferences.  Fixes #5868.
