TARGET_RECOVERY_SKIP_GPG_VERIFICATION doesn't work when building only recovery image

[Ratchanan Srirattanamet]

With "TARGET_RECOVERY_SKIP_GPG_VERIFICATION" set in BoardConfig.mk, building only recovery image will not cause RECOVERY_SKIP_GPG rule in bootable/recovery/Android.mk to be run. This make resulting recovery image still check for GPG signature even "TARGET_RECOVERY_SKIP_GPG_VERIFICATION" is set.

Step to reproduce:
1.Place this line in device's BoardConfig.mk: TARGET_RECOVERY_SKIP_GPG_VERIFICATION := true
2.Buld only the recovery image by running "make recoveryimage"

Expected result:
File etc/system-image/skip-gpg-verification is placed in recovery ramdisk's root and included in resulting image.

Actual result:
File etc/system-image/skip-gpg-verification is NOT placed in recovery ramdisk's root
