udevadm,basic: replace nulstr_contains with STR_IN_SET (#6965)

Browse Source 
STR_IN_SET is a newer approach which is easier to write and read, and which
seems to result in space savings too:

before:
4949848 build/src/shared/libsystemd-shared-234.so
 350704 build/systemctl
4967184 build/systemd
 826216 build/udevadm

after:
4949848 build/src/shared/libsystemd-shared-234.so
 350704 build/systemctl
4966888 build/systemd
 826168 build/udevadm
