icu: Add ptest support

Add following patches.
  - 0001-test-Add-support-ptest.patch
    - Some default paths in test code are invalid at runtime and cause
    - test failures. So add a patch to adjust path to test data for ptest
    - environment.
  - 0001-ICU-23120-Mask-UnicodeStringTest-TestLargeMemory-on-.patch
    - Since ICU-77.1, a test case (TestLargeMemory) that fails to build
    - in a 32-bit environment. So add a patch to skip this test case.
    - This bug has been reported to upstream. See https://unicode-org.atlassian.net/browse/ICU-23120.
Install icu test-suite to run it as a ptest.
Add icu to PTESTS_FAST because it takes 27sec (less than 30sec) to complete on
qemux86-64 with kvm enabled.
