ANDROID: vendor_hooks: modify the function name

Browse Source 
int the commit: https://android-review.googlesource.com/c/kernel/common/+/1699406/
When we build  our vendor driver, report two errors:
1) Symbol too long "trace_android_vh_get_unmapped_area_from_anti_fragment_pool"
2) Symbol too long "trace_android_vh_get_unmapped_area_include_reserved_zone"

So, I shorten the function names:
android_vh_get_unmapped_area_from_anti_fragment_pool  -->  android_vh_get_from_fragment_pool
android_vh_get_unmapped_area_include_reserved_zone    -->  android_vh_include_reserved_zone
