Remove dalvik.vm.usejitprofiles system property.

Disabling profiles is no longer supported. Most of the profile support
has been active even when this property was false, and it won't be
supported in the ART Service.

(cherry-picked from commit 13f37674)

Test: Boot with dalvik.vm.usejitprofiles=false
Test: atest -a android.compilation.cts.AdbRootDependentCompilationTest#testCompile_curProfile
