Quote pattern in 'find' command used to generate modules.load

When a kernel module archive is specified via
BOARD_*_KERNEL_MODULES_ARCHIVE an unquoted wildcard pattern in the
'find' command used to find modules to add to modules.load can result
in a build failure due to shell expansion. Fix this by quoting the
pattern so that kernel modules in $ANDROID_BUILD_TOP don't cause
unexpected build failures.

Bug: 289887845
Test: Define BOARD_VENDOR_KERNEL_MODULES_ARCHIVE for
aosp_cf_x86_64_phone, touch foo.ko &&
lunch aosp_cf_x86_64_phone-userdebug && m succeeds.
